Eclipse RCP application crashes when using scroll in a SWT file browser

My Eclipse(version 3.7.2 32 bit) RCP application crashes on an RHEL 7 machine every time I open file browser and scroll through the folders list to select a folder--by scroll I mean: clicking on the navigation scroll bar on the right side of the file browser, or even typing the name of a folder which will automatically scroll the view to the folder beginning with the letter/s I type. But this doesn't happen if I don't scroll while the file browser is open and just select a folder/file that's already in the view of the browser and this doesn't happen if I scroll anywhere else in my application. Also, this only happens on RHEL 7 (not RHEL 6 or 5, or an AIX, or SUSE Linux) when I am using Exceed, Xming to export the display to a Windows machine. After the crash there is a JVM core dump with this error(please note I see the first 2 warnings below as soon as my GUI launches in Windows, but the crash happens and the exception stack appears on the RHEL console only when I scroll in the file browser):

I see that the module Module=/lib/libgtk-x11-2.0.so.0 is flagged above, but am not sure what's causing this. Also, if it helps, I don't see this module in the /lib path in my RHEL 6 and 5. Can I try installing a different GTK module for RHEL 7 and try, or what else can I do? TIA

This is due to problem with IBM JRE. There has been a bug raised on it and it has been fixed in the latest build of Java 8. APAR IV78992
