Description

Test org.apache.flume.channel.TestSpillableMemoryChannel works fine with OpenJDK, but not with IBM JVM.

With IBM JVM, the test never ends, but it says (in org.apache.flume.channel.TestSpillableMemoryChannel-output.txt): "org.apache.flume.ChannelFullException: The channel has reached it's capacity. This might be the result of a sink on the channel having too low of batch size, a downstream system running slower than normal, or that the channel capacity is just too low. [channel=spillChannel-61d16662-9887-47df-b13e-99193a6d8078]"
and file: "org.apache.flume.channel.TestSpillableMemoryChannel.txt" says:
Tests run: 14, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 192.271 sec
However, stil with IBM JVM, Maven says (ZERO test run):
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

So, there are 2 issues:

• something wrong either with Flume test which blocks or with Maven which does not handle the hang of the test
• some Flume code does not work fine with IBM JVM. I have NO idea what could be the root cause, though it works fine with OpenJDK.
