GUEST: When I was adding a new Tomcat server instance, I opened the file dialogue to specify a private configuration location. In the dialog there I opened the directory tree up to the NetBeans configuration base directory and selected that directory. Now I clicked on the button to create a new directory (for the Tomcat Base) and got this exception.

Is this reproducible for you? I cannot reproduce on Linux (not even on Mac) with JDK1.7u21. Looks like a JDK problem

Trying to add a directory for Tomcat's private configuration

It is sporadically reproducible, i.e. it does not always happen and I cannot pinpoint the conditions to reproduce it.

After a clean install of the latest NetBeans full bundle I could finally "replay" the issue. Therefore I was able to attache the necessary messages.log to the issue.

Comment 7 Ondrej Vrabec 2013-06-28 10:57:47 UTC

same problem as in bug #226248
BasicTreeUI,getPathBounds(tree, path) called from startEditing/ returns null and the return value is not checked
