Hello, Mac OS 10.5 was not officially released yet so oXygen does not officially support it. The NullPointerException that stops oXygen on Mac OS 10.5 with Java 1.5 is caused by a bug in the Apple Java 1.5 virtual machine. If the Java team from Apple will not fix this bug in the Java 1.5 virtual machine that will be shipped with the official Mac OS 10.5 we will try to find a workaround in oXygen code. If you can report this bug to the Apple Developer Connection maybe they will fix it faster. The stacktrace of the NullPointerException is the following and it should not happen when JComponent.getFontMetrics() is called: java.lang.NullPointerException at java.util.Hashtable.get(Hashtable.java:336) at java.awt.Component.getFontMetrics(Component.java:2494) at javax.swing.JComponent.getFontMetrics(JComponent.java:1589) As you already know from this list you can run oXygen 8.2 with Java 1.4.2 on Mac OS 10.5 beta without problems.

Currently the only VM supported is 1.4. When will 1.5, and the current 1.6 (on 10.5) be supported?

I've got it running with 1.5 on 10.4 without any problems.

Best,
