Comment 2 Coty Sutherland 2016-03-04 14:12:46 EST
It looks like this is ASF BZ 56561 from the case. The following two revisions should resolve the issue:


r1597587 | kkolinko | 2014-05-26 09:57:55 -0400 (Mon, 26 May 2014) | 4 lines

Followup to r1597532: check the output of the new test.

It is backport of r1597573 from tomcat/trunk.
