I have posted this question in several forums thinking that it was something that I was doing wrong when exporting my program but I have had no luck and am beginning to think it is a bug rather then something I am doing.  We are deploying our RCP application through a JNLP file.  I am able to deploy my program and it runs great on Linux and Windows, however in Mac I started getting an exception in the libswt-pi-carbon-355.jnilib plugin that would just kill the entire program.  So I changed is so that it would use cocoa since that is replacing carbon anyway.  Now when the program loads from the JNLP file, it throws a NullPointerException in CocoaUIEnhancer.java line: 375 and the program is almost completely unresponsive.  I am sorry if this is the wrong place to report the bug, it seemed to fit better then most of the other places.  Thank you,

Dwain

Reproducible: Always

Here is the stack trace.  The CocoaUIEnhancer is in the org.eclipse.ui.cocoa package.

I don't know if this will help, but I swapped out the org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar for the org.eclipse.equinox.launcher_1.1.0.v20100307.jar, which I pulled from the 3.6M6 build and I no longer see the exception.

I guess the issue was because of a wrong version of jnilib being used. Marking as works-for-me as per Comment# 4
