Initialization of AdCategoryMapper about openrtb-doubleclick HOT 3 CLOSED

I find very strange that concurrent executions of this static block would happen; class initialization shouldn't allow that (unless you have separate classloaders loading the same class...). Do you have stack trace that shows this? And even concurrent loads of the same resource should not cause any problems, they would just create different InputStreams that can read the same thing independently.

Yes, it is strange. I think that the static block is initialized only once per classload. I am not sure what was happening, perhaps multiple class loaders loading the class in the same time?

I am trying to find the stack trace regarding this problem in in my log files, but it will be a hard task. I know that an exception with the mapper text file was happening and an ExceptionInInitializerError was raised in the first time. Then, all the subsequent calls to the AdCategoryMapper were raising a NoClassDefFoundError.

I will try to find the stack trace and post here. If I do not find I intend to close this issue.

Closing the issue. I couldn't find the stack trace with the error.
