-------------------------------------
Looks great and
> other multithreaded tests we might have in the future
I seriously agree with you.
> Make sure failed assertions on test threads are reported

> When running a JUnit test, like TestBSPPeer, if an assertion fails in some
> thread, it is not reported in the console (only failed assertions of the main
> thread are reported). However the assertion failed exception is logged in the
> test report under build/report/tests/.
> Example:
> $ ant test
> jar:file:/home/fdmanana/git/apache/hama/lib/findbugs/ant.jar!/org/apache/tools/ant/Project.class
