Comment 2 Coty Sutherland 2016-03-04 19:12:46 UTC

It looks like this is ASF BZ 56561 from the case. The following two revisions should resolve the issue:

http://svn.apache.org/r1597587
http://svn.apache.org/r1597545

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

It is backport of r1597573 from tomcat/trunk.
