Hi,

I am new to Antlr and AntlrWorks.

I found that AntlrWorks freezes and hangs for ever.

Software:
AntlrWorks 1.2.3,
PL/SQL grammar: from the Antlr.org
http://www.antlr.org/grammar/1209225566284/PLSQL3.g
JRE: 1.5

OS: Window XP Professional, SP2
How to reproduce:
[1]Start AntlrWorks (with lWindowsl ook&feel ). Open the above grammar file.
Verify Grammar. Some errors are encountered. Click Console tab. Antlrworks
freezes forever. Screen does not refresh. I have to kill the application
(javaw) to end the program.
[2]Start AntlrWorks (with Java lMetal ook&feel ). Open the above grammar
file. Verify Grammar. Some errors are encountered. Click Console tab.
Antlrworks works. Now start debugger. Antlrworks freezes forever.
As you can see, by just changing the look and feel,Antlrworks worked while
tabbing to Console, but then it got hung at another point.

Thanks.

Devang
