Exception when ThreadLocal.set() is called.

[shahabas shabeer]

Hi,

My application throws a java.lang.Exception when it call ThreadLocal.set() method. This happens only during load test with 1000 concurrent virtual users. I never got this error during development and could not reproduce in my development machine. So I guess the issue is with thread management. Should I call this method in a thread safe manner?. What would happen if I did not synchronize the method?. Will the application throw java.lang.Exception if two threads try to update this value at the same time? Any help would be highly appreciated.

Thanks

Is there no message associated with the exception? If not, are you sure that your code isn't swallowing and re-throwing a more informative exception?

Nope.. There is no clear message in the exception. I do have a try-catch block but I am printing the entire exception details using printStackTrace() method.

That sounds, ummm, suspicious. I suggest posting the complete stack trace, along with the exact JDK version number and OS that you're using.
