This happened in jdk 9 dev nightly with b89-2015-10-23.
OS is Windows 8.1 X64

There is a similar history bug JDK-8078577, but if we look at stacktrace in detail, they are different. So filed a new bug for this failure.

See the following test output:
----------System.out:(1/11)----------
Test1: OK
----------System.err:(20/1122)----------
