[fedora-java] java very slow on arm

[Orion Poplawski]

I'm building protobuf 3.1.0 for rawhide.  The arm build is incredibly slow.

See http://koji.fedoraproject.org/koji/taskinfo?taskID=16512668

Entire x86_64 build took 21 minutes. Steps in the isValidUtf8Test look like:

Nov 18, 2016 4:18:01 PM com.google.protobuf.IsValidUtf8TestUtil testBytes
INFO: Round tripped 18304 of 65536

INFO: Round tripped 18304 of 65536
Nov 18, 2016 4:18:02 PM com.google.protobuf.IsValidUtf8TestUtil testBytes

It's been running for over 11.5 hours on arm, and test steps look like:

and has increased in time to:

Have there been any other reports of issues like this on arm?
