OutOfMemory when running test application for bug 751 on Hazelcast 1.9.4.6

[Rob Burgers]

Hi,

Hazelcast 1.9.4.6 contains a fix for:
http://code.google.com/p/hazelcast/issues/detail?id=751

However when I run the test application contained in that bug it fails
after 79 attempts (I tried twice) with an OutOfMemory exception (see
below).
When I run the same test application on Hazelcast 1.9.3 this issue
does not occur.

Should I be worried about this? The test application may be a bit
strange in nature, but I wonder if the issue may surface in a more
common use case as well.

Note: There may be other instances and versions of Hazelcast running
on my network.

Best regards,
Rob Burgers

We finally figured out the problem and fixed it. The fix is in trunk.

Thanks too Eddy van Oosterbosch.

Hi Fuad,

Thank for the update.
Hopefully there will be a full release including this fix soon.

Eddy and I are actually colleagues (the solution is completely his).
