Description dave_charles 2012-11-27 16:49:51 UTC 
The implementation of Repository$MainFS.provideLayer(List<URL>) assumes that  Thread.currentThread().getContextClassLoader() will never return null.

A non-null return value is the typical case, but I have received numerous reports from other developers of an NPE on the very next line, suggesting that Thread.currentThread().getContextClassLoader() has indeed returned null.

I have never seen this behavior myself, but I have received enough reports from different sources to believe it is true, and it seems to happen only when org-openide-filesystems.jar is used outside of an RCP application.

It appears that Sun/Oracle has already reviewed this return-value issue and decided it is not a bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4155645
