I have been using fakeSMTP-2.0.jar successfully to do my Java development from last 4-5 years. However, from last two days, I have been repeatedly getting the following error message and the application fails to start:
java.lang.IllegalAccessError: class com.nilhcem.fakesmtp.FakeSMTP$1 (in unnamed module #0x12cc3010) cannot access class com.apple.eawt.Application (in module java.desktop) because module java.desktop does not export com.apple.eawt to unnamed module #0x12cc3010
I have always ran the application as sudo on Mac High Sierra (10.13.6) and with Java 8 (jdk1.8.0_261.jdk).
Would appreciate any insight into the issue.

This is the error:
lib/openNews.dart:134:28: Error: The method 'showSnackBar' isn't defined for the class 'ScaffoldState'.
- 'ScaffoldState' is from 'package:flutter/src/material/scaffold.dart' ('../../Documents/flutter/packages/flutter/lib/src/material/scaffold.dart').

If I use my PC to run the exact same project file on VSCode, it runs on emulator just fine with no error messages, but if I run it in my mac, it makes this error.
Interestingly this wasn't an issue yesterday because it ran fine that day, but today is weird.
So I deployed a build that runs perfectly on my windows machine to a Linux box earlier this morning and when I tried to start the service I got the error below.
Caused by: java.lang.IllegalStateException: AutoConfigure cycle detected between org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration and org.springframework.boot.autoconfigure.cache.CacheAutoConfiguration
So I copied all of the libs from the target machine to my windows machine and ran the application from a windows command prompt. The application started fine.
So I eventually remote debugged the application and came up with a very interesting issue that has got my head scratching.
But before I went further I switched on -verbose to make sure the class in question was being loaded from the same jar in both windows and linux.
[Loaded org.springframework.boot.autoconfigure.cache.CacheAutoConfiguration from file:/apps/IRDrsudbld/<project structure>/lib/spring-boot-autoconfigure-1.5.8.RELEASE.jar]
And it is.
So when I debug in linux and look at the metadata for the two classes
this = {AutoConfigurationSorter$AutoConfigurationClass#3645}
className = "org.springframework.boot.autoconfigure.cache.CacheAutoConfiguration"
metadataReaderFactory = {ConcurrentReferenceCachingMetadataReaderFactory#3637}
autoConfigurationMetadata = {AutoConfigurationMetadataLoader$PropertiesAutoConfigurationMetadata#3611}
It states the following
"org.springframework.boot.autoconfigure.cache.CacheAutoConfiguration.AutoConfigureBefore" -> "org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration"
"org.springframework.boot.autoconfigure.cache.CacheAutoConfiguration.AutoConfigureAfter" -> "org.springframework.boot.autoconfigure.data.couchbase.CouchbaseDataAutoConfiguration,
org.springframework.boot.autoconfigure.hazelcast.HazelcastAutoConfiguration,
org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration,
org.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration"
But the line in bold is completely wrong as the 1.5.8 source code has the annotations below.
#Configuration
#ConditionalOnClass({CacheManager.class})
#ConditionalOnBean({CacheAspectSupport.class})
#ConditionalOnMissingBean(value = {CacheManager.class},name = {"cacheResolver"})
#EnableConfigurationProperties({CacheProperties.class})
#AutoConfigureBefore({HibernateJpaAutoConfiguration.class})
#AutoConfigureAfter({CouchbaseAutoConfiguration.class, HazelcastAutoConfiguration.class,
RedisAutoConfiguration.class})
#Import({CacheAutoConfiguration.CacheConfigurationImportSelector.class})
public class CacheAutoConfiguration {
Has anyone seen an issue like this before as I am completely mystified as to what is happening here.
Thanks
After debugging the code it appears that one of the internal shaded jar files contains a spring-autoconfigure-metadata.properties which is for spring boot 2. When the application is executed on linux this jar file is loaded after the spring boot autoconfigure one and replaces the
org.springframework.boot.autoconfigure.cache.CacheAutoConfiguration.AutoConfigureAfter
Property with one that is not valid for the spring boot version in my application.
At least I have found out what the problem is.
I am trying to run simulte with omnet 5.0 and inet 3.4. I build in with terminal.
When i try to run tutorial simulation via
Right-clicking on simulations/tutorial/omnetpp.ini and "Run as Omnet simulation", it gives me following error
Error in module (omnetpp::cModule) SingleCell (id=1) during network setup:Class "LteChannelControl" not found -- perhaps its code was not linked in, or the class wasn't registered with Register_Class(), or in the case of modules and channels, with Define_Module/Define_Channel().
Now I have also checked LteChannelControl class .cc and it infact has the Define_Module(LteChannelControl) inside.
If you have any idea how to resolve this, it will be eppreciated.
Thanks
the problem was solved by running simulations via terminal. It appears that using Omnet gui for simulte gives alot of problems. Simulte wants to be used via terminal or cmd instead.
I have followed step by step the tutorial to install Veins, but when I tried running the example scenario (final step) I ended up with the above error.
The whole error was:
Error in module (cModule) RSUExampleScenario (id=1) during network
setup: Class "Veins::ObstacleControl" not found -- perhaps its code
was not linked in, or the class wasn't registered with
Register_Class(), or in the case of modules and channels, with
Define_Module()/Define_Channel().
TRAPPING on the exception above, due to a debug-on-errors=true
configuration option. Is your debugger ready?
Simulation terminated with exit code: -2147483645 Working directory:
C:/Users/user/src/veins-4.3/examples/veins Command line:
../../../omnetpp-4.6/bin/opp_run.exe -r 0 -n .;../../src/veins
--tkenv-image-path=../../images -l ../../src/veins omnetpp.ini
I don't think I have missed a step during the tutorial as I have tried it two times. I did not make any change in anything, I've just strictly followed the tutorial like a robot, so I cannot provide an MCVE with more details than the tutorial.
Here is what I'm using:
- Windows 7 Pro 64 bits
- SUMO 0.25.0 64 bits
All other steps of the tutorial successfully worked until the final step.
I assume this error occurs when running Veins via the OMNeT++ IDE. Or, if you have compiled it with GCC (The error does not happen if you use CLANG)
There are two ways to bypass this error:
Use the .run as executable from your examples directory, which calls veins/run and includes all the required libraries:
Use opp_run as executable and set dynamic libraries to the directory where libveins.so is located (usually src/veins)
PS: to answer #ChristopSommer questions: Veins::ObstacleControl appears in opp_run -l src/veins -h classes
This could be a solution too, but I never tested it: Compiler flags in Eclipse
I have installed EmguCV 2.4.2.1777. I have a 32-bit windows 7 so I installed it using the installer. Now I am trying to write a simple code to capture a webcam's video in a window in C#.
The problem is after during execution I am getting the following famous error:
A first chance exception of type 'System.DllNotFoundException' occurred in Emgu.CV.dll
A first chance exception of type 'System.TypeInitializationException' occurred in Emgu.CV.dll
An unhandled exception of type 'System.TypeInitializationException' occurred in Emgu.CV.dll
The file Emgu.CV.dll is present in the folder. I don't understand why its giving that error.
I tried all the checks which are suggested by fellow stackoverflow users and also many other references:
1) Installed MSVCR: MSVCRT 10.0 SP1 x86
2) copied the OpenCV dlls to the execution directory
3) I also have a 32-bit OS. So that also should'nt be an issue.
But when I checked for dependencies, I faced a problem:
I used DependecyWalker to open cvextern.dll and found the following dependencies missing:
NVCUDA.DLL
API-MS-WIN-CORE-COM-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-ERROR-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-ROBUFFER-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-STRING-L1-1-0.DLL
API-MS-WIN-SHCORE-SCALING-L1-1-0.DLL
DCOMP.DLL
IESHIMS.DLL
It also gave the following:
Error: At least one required implicit or forwarded dependency was not found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
Please help me out with the exception. Thanks in advance.
I copied all the dll files from C:\Emgu\emgucv-windows-universal-gpu 2.4.9.1847\bin\x86 to a folder called includes in my project and updated the "Copy To Output Directory" Option for these DLLs to "Copy Always" and it got rid of this issue.
