It looks like the resource tree is corrupt. Moving to Platform/Resources for comment.
I think this is a bug in your VM or class libraries. The NullPointerException comes from inside the implementation of String.indexOf(int). There is nothing the caller could do wrong to generate such a problem. The ArrayStoreException is also impossible. Here is the line of code: segments[nextFreeSegment++] = node.getName(); The node.getName() method returns type String, so the only possible return values are String, Object, or null. All three would be assignable to segments[], which is of type String. Can you reproduce this without the -XX:+UseConcMarkSweepGC argument?
I'll test without the -XX:+UseConcMarkSweepGC and try installing my JRE. Is 1.4.2 the recommended JRE or are we on 1.5 these days? Further I've got the following error whihc differs slightly: !ENTRY org.eclipse.jface 4 2 2005-05-27 16:02:56.758 !MESSAGE Problems occurred when invoking code from plug- in: "org.eclipse.jface".
