[rules-users] Parsing problems using a DSL

[drdaveg]

I have some more incite into what might be causing the problem.  Once I
remove the drools.package file - which shouldn't be needed since the imports
and expander are in the .dslr file - and have a trivial example - I can see
an "DSL Rule Translation: Array out of bounds" exception generated in
Eclipse several *minutes* later.  My DSL makes no mention of arrays and, in
this simplest case, am generating 

object1 : Car()

where object1 and Car are mappings.  Once the exception is generated and the
dialog box clicked on, you can see the correct translation in the DLR file. 
Thus, I believe 

1. the translator is grinding in an infinite loop, probably just before the
file is closed and 
2. The exception closes the (correctly translated) file.

Is there some token (other than "end") that should be included in the .dslr
file to ensure the file closes properly?  I don't see any control characters
present in the file when I open it in a variety of editors.

On antlr, I was referring to an article at
http://blog.athico.com/search/label/DSL%20regexp%20antlr that discusses the
development of Drools.  Thanks!
