[aspectj-users] Load-time weaving into Eclipse plug-ins

[Jan Ploski <Jan.Ploski@xxxxxxxx>]

Hello,

I'd like to weave a compiled aspect into classes that belong to Eclipse 
plug-ins (executed inside of an Eclipse workbench). I start the workbench 
like so:

CP=/home/jploski/eclipse-3.2.1/startup.jar
CP=$CP:/home/jploski/workspace-3.2/tpmon1-ant/external-libs/aspectjlib.jar
CP=$CP:/home/jploski/workspace-3.2/tpmon1-ant/external-libs/aspectjrt.jar
CP=$CP:/home/jploski/workspace-3.2/tpmon1-ant/external-libs/aspectjtools.jar
CP=$CP:/home/jploski/workspace-3.2/tpmon1-ant/external-libs/mysql-connector-java-5.1.5-bin.jar
CP=$CP:/home/jploski/workspace-3.2/tpmon1-ant/dist/tpmonLTW.jar 

/usr/local/jdk1.6.0_02/bin/java \
    -Dorg.aspectj.weaver.showWeaveInfo=true \
    -Daj.weaving.verbose=true \
 
-javaagent:/home/jploski/workspace-3.2/tpmon1-ant/external-libs/aspectjweaver.jar 
\
    -ea -Xmx256M \
    -classpath $CP \
    org.eclipse.core.launcher.Main \
    -launcher /home/jploski/eclipse-3.2.1/eclipse \
    -name Eclipse \
    -showsplash 600 \
    -product org.eclipse.sdk.ide \
    -data /home/jploski/workspace-3.2.debug \
    -configuration 
file:/home/jploski/workspace-3.2/.metadata/.plugins/org.eclipse.pde.core/Runtime 
Workbench/ \
    -dev 
file:/home/jploski/workspace-3.2/.metadata/.plugins/org.eclipse.pde.core/Runtime 
Workbench/dev.properties \
    -pdelaunch -os linux -ws gtk -arch x86

In the console output, I can see several classes being instrumented, but 
then there are messages such as:

[StartupClassLoader@34ab7a] info AspectJ Weaver Version DEVELOPMENT built

[DefaultClassLoader@e523ed] info no configuration found. Disabling weaver

org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader@e523ed
...

Accordingly, the classes of my plug-in are not instrumented at all.

How can I enable weaving for these additional class loaders? Better yet, 
how do I configure weaving so that any loaded class is instrumented if it 
matches the name pattern, regardless of which class loader it came from?
