Subject: [Bug SWING/21064] New: StyleContext.addStyle causes NullPointerException
Date: Sat, 16 Apr 2005 23:02:00 -0000 [thread overview]
Message-ID: <20050416230239.21064.bothner@gcc.gnu.org> (raw)
The (to-be-shortly) attached testcase (which works with JDK 1.4.x)
causes a NullPointerException:
$ gcj -o SwStyle SwStyle.java --main=SwStyle -g
$ ./SwStyle
Exception in thread "main" java.lang.ExceptionInInitializerError

This is using the gcc-4.0 branch; I haven't tested head.
(This testcase is simplified from JEmacs.)
