double-initialization of spring beans in jetty 7.1.4 - spring

When I start a webapp that has a spring configuration in jetty, I see two calls to initialization (#PostConstruct methods). web.xml declares a ContextLoaderListener and provides contextConfigLocation.
This seems wrong. (spring 3.0.3). Is there something I've done?
EDIT
My web.xml calls out both the DispatcherServlet and the org.springframework.web.context.ContextLoaderListener. If I remove the later, I stop seeing two initializations --- but my app fails in the jetty-maven-plugin with
No WebApplicationContext found: no ContextLoaderListener registered?
EDIT 2:
Got it. The dispatch servlet will find some context files by conventional name (*-servlet.xml), and so calling that file out again in the contextConfigLocation led to it being loaded twice.

Actally, you have two Spring application contexts:
Context loaded by ContextLoaderListener from the XML files specified by context-param named contextConfigLocation (or applicationContext.xml by default).
Context loaded by DispatcherServlet from the XML files specified by the dispatcher servlet's init-param named contextConfigLocation (or <servletname>-servlet.xml by default).
The former is a parent context of the latter.
So, you somehow got a definitions of the same bean in both contexts (perhaps, both contextConfigLocations point to the same XML files).

The error message JVM pause points to the low heap size assigned to carry out its operations
Detected pause in JVM or host machine (e.g. a stop the world GC, or JVM not scheduled): paused approximately 2936ms: no GCs detected.
You should increase the CM server heap size. It can be set at CM server host in /etc/default/cloudera-scm-server change -Xmx option to a higher value preferably double the size. Save changes and restart Cloudera Manager.

Don't know if it will work, but you might want to consider having the workers call a function that looks something like this:
function profile_function(func, args...)
Profile.clear()
ret = #profile apply(func, args)
pdata = Profile.retrieve()
ret, pdata
end
pdata should contain the profiling data from that worker. You should be able to view it in ProfileView.

You may try VTune Amplifier (https://software.intel.com/en-us/intel-vtune-amplifier-xe) to profile Julia code at function level as described at https://software.intel.com/en-us/blogs/2013/10/10/profiling-julia-code-with-intel-vtune-amplifier. You may also need to apply a patch to LLVM (https://gist.github.com/ArchRobison/d3601433d160b05ed5ee) to workaround source level performance information bug to get correct data at a source line level

Method postToSystem() is automatically called on deployment in spring

I have a simple Spring application, with a bean which contains a method with the name postToSystem(parameters) without any annotations and it is automatically called on deployment (and throws an exception). Could someone explain me what is the problem here? Is it the method name? The stacktrace when it is called is:

possible dead-lock with nested transactions in grails service

I have a transactional grails service which is doing some (long running) processing. While processing, I would like to update a "percentComplete" value (which will ultimately be used to display a progress bar on the front-end). This obviously has to be written immediately (i.e. not as part of the current transaction), otherwise it is of no value.
Hence, I'm using the Grails Transaction Handling Plugin and specifically the "withNewTransaction" method to start up a new transaction, within which the percentComplete attribute is updated.
My problem is that, second time around in to the "updatePercentComplete()" method, the application hangs when attempting to exit the "withNewTransaction" method (presumably when it is trying to commit the transaction).
Notes:
if I comment out the session flushing in the main service method, there is no problem (btw, this flushing, along with clearing, is required for performance reasons in my real application)
using the hsql database, there is no problem (see DataSources.groovy).
also using the grails executor plugin, but I don't think this is causing any problems in itself (see the LibraryServiceTests, which also hangs and bypasses the plugin).
Where should I go looking to debug this problem? Maybe there are some log levels I can set in grails/hibernate somewhere to pin-point what is happening?
The thread doing the work seems to be getting stuck trying to read from a socket, see stack trace below. There don't appear to be any actual deadlocks in the JVM itself.
Here is my service class, link to full project below:
package withtransactiontest
class LibraryService {
static transactional = true
def sessionFactory
def loadBooks(library) {
int repeat = 5
repeat.times {
updatePercentComplete(library, it * (100 / repeat))
// Simulate some long running process in order to be able to see percentComplete getting written to DB.
Thread.sleep(2000)
// Update some property (within the default transaction)
library.name += "x"
library.save()
// Comment out the following, and the current method will complete successfully.
def session = sessionFactory?.currentSession
session?.flush()
}
library.percentComplete = 100
library.save()
}
void updatePercentComplete(library, val) {
println "before new transaction"
Library.withNewTransaction {
println "Percent complete: " + val
library.refresh()
library.percentComplete = val
library.save()
println "after save"
// Hang here, second time around.
}
println "Percent complete transaction committed"
library.refresh()
}
}
Link to grails project with integration test case which re-creates the problem

Workaround is to introduce a new domain class, Progress, which has the property percentComplete and belongsTo Library. This is updated in the new (nested) transaction, rather than the Library instance itself.
