Description Eric Nickell CLA 2005-05-20 13:34:01 EDT 
The following (probably illegal) construction generates a series of pop-up 
windows complaining of an illegal error.

public class ByPlayer extends CategorizableReportable<ByPlayer.SubclassA, 
ByPlayer.SubclassB> {

}
Comment 1 Olivier Thomann CLA 2005-05-20 14:32:38 EDT 
Test case to reproduce with latest:

class CategorizableReportable<T, U> {}
public class X extends CategorizableReportable<X.SubclassA, X.SubclassB> {

}

Exception is:


java.lang.NullPointerException
