[antlr-interest] [ANTLRWorks] Locking assertion failure ?!?

[Simone Tripodi]

Hi Folks,
I'm trying using ANTRL Works 1.1.7 on Ubunbtu Linuz with Sun's JDK
1.5.0_15; when launching ANTRL Works, a message appears:

java -jar antlrworks-1.1.7.jar

The splash-screen appears as usual, but after a totally empty window
appears; if I try clicking on it, an exception is thrown:
