#604 PerlValidator.underlineError exception

[Anonymous]

Using stable version 0.5.46 on a virgin install of IDE for Java Developers Version: Helios Service Release 1 Build id: 20100917-0705.
Using cygwin perl (set up properly in EPIC settings). Created a Perl project, entered some trivial code, ran a debug session everything worked fine.
Upon deliberately putting a syntax error in the code and saving, the validator threw an exception (stack trace from error log follows):
