Re: Strange IllegalAccessError w/FastClassByCGLIB class

[Jason Dillon]

 I will look at it more... I'm not familiar with the proxy gen in G  
yet... but a race condition sounds likely since this problem only  
shows up in multithreaded concurrency test.

Is there an existing test for G somewhere?  I can commit my work on  
JMeter components if that would be helpful.

I don't, but have you looked up what it is in StatelessInstanceFactory
that generates that message?  Perhaps we have a race condition?

I see these exceptions when running concurrency tests; and once this
occurs the application is blown and I have to restart G to recover.
