Alexey Panteleev commented on HTTPCLIENT-1173:
----------------------------------------------
Even though it happens on a daily basis in our complex daemon it's kinda tough
to create a simple testcase to post here.
I really don't understand which threads and in which combination have to run to
reproduce this.
What I know though is that once this happens in one thread (httpclient
connecting to an EWS server) this starts happening in all other threads
(connecting to similar EWS servers). As if some kind of memory corruption
happened and affected all following executions :(
How can ArrayIndexOutOfBoundsException happen in the for loop itself? Another
thread changing the array? But then a negative index?
I use Debian + JVM 6. Googleing JVM bugs now ...
