Just ran the {{BufferSpillerTest}} for 10h in a loop. No failure occurring.
Hard to reproduce on a setup other than Travis...

Stephan Ewen commented on FLINK-2464:
-
Can you paste the build on which that happened? I have the suspicion that there
may be an issue with Java 6.
The {{BarrierBufferMassiveRandomTest}} sometimes crash the JVM on Java 6
builds, which almost looks like the I/O code causes a segfault, or a similar
critical issue. Since we are not using any unsafe stuff in that code, it may be
a Java issue.
If the barrier buffer I/O is affected by that, it may also explain the failures
of the {{BufferSpillerTest}} and the {{StreamCheckpointingITCase}}.

It seems very strange, because that check means that for a buffer, the first 57 bytes are as expected and the 58th is unexpected. And the length is correct as well. I have no idea how that could happen...
