Yes.  Please file one at http://icedtea.classpath.org/bugzilla

7175845 is present in the 2.1.x, 2.2.x and 2.3.x series of releases,
and the first two don't show this issue.  Something, however, has caused
it to regress again in 2.3.x, as I'm seeing the same thing here.

I don't see it in 3.x but then it's hard to compare as the OpenJDK 8 build
system is completely different.
