Francesco Nigro commented on ARTEMIS-1223:
------------------------------------------
[~eduda] It is something that could happen only on tests.
The TimedBuffer allocates space off JVM heap and is allocated only one time in
the whole lifetime of a broker.
During the tests there are multiple allocations/deallocations of it and it
generates some problem depending on how the JVM's GC handle the native
deallocations using the ByteBuffer Cleaner.
My proposal would be to let just the tests allocates it on heap, but is
important to not makes it always in that way because it is faster than the
previous one partially due to its off heap allocation.

> I see a lot of OutOfDirectMemoryError \[1\] in Artemis test suite when it
> runs on IBM JDK. I don't see it with Oracle or OpenJDK.
> For reproducing the issue run {{LargeMessageCompressTest}} on IBM JDK.
