Re: JBuilder 2005 & Java 1.5?

I've just upgraded Java to 1.5 release 4, and JBuilder 2005 Foundation, which had been working fine with 1.4.2,  has stopped working.  It freezes at the splash screen, and the following is displayed in the console:

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: org/apache/crimson/jaxp/DocumentBuilderFactoryImpl

This exception should have been resolved with the most recent developer preview of Java 1.5.


 (After updating to JBuilder 2005 update 4)
First, when I run JBuilder I now get this error:  Exception in thread "main" java.lang.NoSuchMethodError: java.awt.Window.isAlwaysOnTop()Z
Since isAlwaysOnTop() is new for 1.5,  I presume means that JBuilder is stuck on 1.5.

This is because JBuilder 2005 update 4 adds Borland's own implementations of the AWT classes (java.awt.*, and some javax.swing classes) based on 1.4.2 to the bootclasspath. At the same time, JBuilder uses a custom launcher which always loads the VM using the CurrentJDK link. Since the VM is still running 1.5.0, and peers are still 1.5.0, but the actual AWT classes are 1.4.2, you get this exception. 

This should be reported to JBuilder as a bug; either they should not ship their own copies of java.awt.Window (etc), or their launcher should force 1.4.2 instead of going through CurrentJDK.
