why cant i get spring load time weaving to work - spring

Question

i have been trying to get an example #Configuration build to work (in groovy) so i can trigger dependency injection outwith a spring container but all i get is error about the -javaagent which i cant seem to fix
I have a beanConfig class like this
#Configuration
#EnableSpringConfigured // should turn on AnnotationBeanConfigurerAspect
#EnableLoadTimeWeaving (aspectjWeaving=AspectJWeaving.ENABLED) // switch on for this context
class BeanConfig {
then a sample class i will call new on and try and get the injection oustide the spring container, where the diSource bean is declared in the above configuration class
`
#Configurable (autowire=Autowire.BY_TYPE, dependencyCheck=true)
class ExtDI {
#Autowired DISource diSource
def say () {
println "ExtDI : diSource set as " + diSource.name
}
}
`
in my sampler class i call this to try and trigger the injection
`
...
static void main (String[] args) {
AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(/BeanConfig.class/)
ctx.scan ("com.softwood")
ctx.refresh ()
....
//trigger LTW injection
ExtDI ext = new ExtDI()
ext.say()
`
on the class path i have aspectjeaver-1.6.10.jar, aspectjrt-1.6.10.jar, spring-xxx-3.1.4.jars, etc
heres my gradle depdency listing
dependencies {
compile 'org.codehaus.groovy:groovy-all:2.1.7'
compile group: 'commons-collections', name: 'commons-collections', version: '3.2'
testCompile group: 'junit', name: 'junit', version: '4.+'
compile "org.springframework:spring-core:${spring_version}"
compile "org.springframework:spring-beans:${spring_version}"
compile "org.springframework:spring-context:${spring_version}"
compile "org.springframework:spring-aspects:${spring_version}"
compile "org.springframework:spring-aop:${spring_version}"
compile "org.springframework:spring-instrument:${spring_version}"
compile "org.aspectj:aspectjrt:1.6.10"
compile "org.aspectj:aspectjweaver:1.6.10"
compile "cglib:cglib:2.2"
}
in the eclipse project runtime for the vm args i have
-javaagent:C:/Users/802518659/aspectjweaver-1.6.10.jar
and have tried same with spring-instrument-3.1.4.jar and had same problem.
when i run the project i get this error

`
which tells me that my application can't instrument the java classloader - despite the fact i start it with the -javaagent:spring-instrument-xxx or aspectjweaver.jar - both fail
So what am i doing wrong - this is really beginning to bother me - i can get ordinary injection within the context to work (no LTW) but really wanted to get this injection outside the container to work
what am i doing wrong

Answer 1

took some time but figured out where it was going wrong
corrected on another post on spring forums see
http://forum.spring.io/forum/spring-projects/container/724426-cant-get-aspectj-load-time-weaving-to-work
also i added a longer note to my blog here
