Dear Julien,
I remember having the same kind of problems. Please check the way we
fixed it here:
http://quantum.cvs.sourceforge.net/quantum/quantum-plugin/src/com/quantum/editors/SQL2ScannerWithLexer.java?view=log
If I remember correctly, the setRange is sometimes called with illegal
values for offset and/or length.
Happy coding,
Jan
