Re: [aspectj-users] setting -javaagent:aspectjweaver.jar results inClassCircularityError

I have bundled the xml in a jar under META-INF. I am pretty sure the
jar is in classpath; if I don't specify javaagent (so I don't see the
error) then the win32 process locks the jar and does not allow
removing it.

I noticed that the jar created by the iajc task has
META-INF/aop-ajc.xml not META/aop-ajc.xml so I made that change, still
I get the same error.

I tried the jar with a simple stand-alone java program and it does
show a few info messages from aspectjweaver, the last one being "no
aspects registered. Disabling weaver for class loader
sun.misc.Launcher$AppClassLoader@17943a4. ". None of these show up in
my work environment.

I also tried a simple javaagent with a do-nothing transformer that
prints the name of class. This works as expected both in the test and
work environment.

So:

work env + aspectjweaver => error, no log messages
work env + aspectjweaver + aop.xml excludes => error, no log messages
test env + aspectjweaver + aop.xml excludes => no error, got log messages
work env + test javaagent => no error, log messages
test env + test javaagent => no error, log messages

So the only combination that does nothing right is my work env with
aspectjweaver; and adding META-INF/aop.xml does not change anything.

What does this mean? I have no clue. But I am hoping that you do, or
at least can figure out some next steps for investigating.

Thanks,
- hemal

PS: Does it matter that there is a custom classloader? I am sure it
was there from before when my aspects used to work, but something may
have changed in the env resulting in combination of that change and
custom classloader to trigger this error.
