please attach thread dump as file, it's hard to read when it's part of Description, thanks.
It is problem of JDK it hangs at sun.awt.datatransfer.ClipboardTransferable.getClipboardData(NativeMethod). Please file bug to JDK.
BTW this happens to me from time to time on Linux - seems to be a problem with copying a large block of text (from Emacs?) and then giving focus to NetBeans. Easily reproducible using any Java app. See message on nbdev.
I filled a bug against jdk see: http://developer.java.sun.com/developer/bugParade/bugs/4818143.html
Thanks!
