when changing the constructor name from CopyOfAboutDialog to AboutDialog, there is no build error
it was not the 20115 but 11219. Seems to work in 20115
Kent: Did you make any change in this area recently that would solve this problem ?
Yes ClasspathJar.java was changed to better protect against this NullPointer problem. The change was not released until the Jan. 8th build.
