Getting SIGSEGV while using createInstanceWithContext()

[Kandarpa Malipeddi <ka...@persistent.co.in>]

Hi All,

We have compiled Apache OpenOffice3.4 source code and generated RPMs for core, URE and SDK. We have installed these RPMs.

While using the Apache OpenOffice 3.4 ure and sdk we observed following:
In one of our test cases we call "createInstanceWithContext()" function and this function lead to segmentation fault.
We ran this test case with VALGRIND tool and following are our observations:
                There is an invalid read in JavaLoader.
 Please find the Trace given below:

Please let us know any points on this and also let us know workaround on this issue.

Note: We are checking the correctness of "context" (using context.is() != NULL) before calling the function "createInstanceWithContext()".

Thanks in advance
