Various errors when accessing ComplexTypeArrayOffHeapPool

[glebreutov]

Hi,
After previous issue, I made some tests and now I getting other mysterious errors.

At each run I'm randomly getting or exception

Exception in thread "main" java.lang.AbstractMethodError: tr.com.serkanozal.jillegal.offheap.pool.impl.ComplexTypeArrayOffHeapPool.getAt(I)Ljava/lang/Object;
    at impl.jilligal.HashVO.getVoarrayElt(Unknown Source)
    at impl.jilligal.HashVO.get_node(Unknown Source)
    at impl.jilligal.HashVO.long_value(Unknown Source)
    at samples.OneMillionObjects.readRandomValues(OneMillionObjects.java:48)
    at samples.OneMillionObjects.main(OneMillionObjects.java:128)

or JVM crash

Code that causes crash:

Getting object:

HashVO source can be found here: https://github.com/glebreutov/jilligal-test/blob/master/src/impl/jilligal/HashVO.java

Here you can find whole source of test https://github.com/glebreutov/jilligal-test/blob/master/src/samples/OneMillionObjects.java

Please tell if you need some additional info.
Thanks in advance.

Forget to add important note: everything works fine if I allocate HashVo on heap
