Description vtec 2007-07-18 08:34:44 UTC

May be a JDK bug but also may be a result of some later netbeans customizations. While searching for a jar-file to be
added into project's classpath using JFileChooser popped out by "Add Jar/Folder" button I received nasty NPE from
JFileChooser. 

java.lang.NullPointerException

Really looks like a Swing bug, but core/windows code is also involved. Please investigate.

Hmm, sorry but without reproduction steps I can do nothing here, can't fix it and can't report to JDK because of random
nature of the bug. Feel free to reopen with reproducible scenario, thanks.
