Error while loading .cgt or .egt in Java

[Andrei Arusoaie]

Hello!

I've been using Gold a lot and I very happy about it. Well, usually, I
used it for small grammars and it worked perfect until I've developed
grammar for OCL (available here: http://students.info.uaic.ro/~andrei.arusoaie/grammar/ocl-2.grm)
The problem is that I cannot the generated tables .cgt or .egt in
Java. The error I receive when I'm trying to load .cgt file is the
following:

Exception in thread "main" java.lang.NullPointerException
at goldengine.java.GOLDParser.loadTables(GOLDParser.java:582)

at main.Executor.execute(Executor.java:77)
at main.Main.main(Main.java:42)

A similar error I get for the .egt:

Exception in thread "main" java.lang.NullPointerException

It's true that that I have some shift-reduce conflicts but those are
solved by the Builder and I can generate the tables. I've tried to use
the tables in C# and it worked, but I can only use Java in my
project. :)

Thanks,
