Description andreas.nautsch CLA 2011-07-20 12:11:34 EDT 
Build Identifier: I20110613-1736

I'm developing an eclipse plugin which displays an Excel Worksheet in an Eclipse Editor.
It worked before 3-4 Weeks.
I did no Eclipse updates, just some Windows and JVM.
Now it's broken and there is a log-File created which says "A fatal error has been detected by the Java Runtime Environment: EXCEPTION_ACCESS_VIOLATION (0xc0000005)" at swt-win32-3735.dll+0x2eb2b.
The Eclipse crash occurs after calling dispatch() of the OleClientSite Object.
I changed my Eclipse Version to the current one and updated my JVM.
Same problems.

Reproducible: Always

Steps to Reproduce:
1.create new Eclipse Plugin Project
2.create a view or editor with an OleFrame
3.OleControlSite controlSite = OleControlSite(OleFrame, SWT.NONE, "Excel.Sheet", input);
4.OleClientSite site = (OleClientSite) controlSite;
5.site.dispose();

Hi Andreas,

I facing the same issue. Could you elaborate a bit more on how to solve the problem? What do you mean with "several disposes" ? I thought it is necessary to dispose the automation once they are not relevant (used) anymore.
