Java Version: java version "1.7.0-ea" Java(TM) SE Runtime Environment (build 1.7.0-ea-b72) Java HotSpot(TM) Client VM (build 17.0-b01, mixed mode) Platforms: WindowsXPpro, Solaris-sparc10 Problems: I launch the Java2Demo within b72, when I clcik Paint tab, it threw exceptions as followings, that only happens in b72-2009-09-17 build, but b72's previous builds are fine, meaning b72-2009--09-16 and previous are OK, so looks like there is a regression in b72-2009-09-17 build. To reproduce the problem: 1, Go to RE site to launch the Java2Demo by using the b72-2009-09-17 runtime 2, Click Paint, you will see the following exceptions.
