[groovy-user] Groovyc generates a "java.lang.SecurityException" with Vista

[Fred Janon]

I just installed Groovy 1.5.4 with the Windoz installer on Vista, opened a cmd window and typed "groovyc" as I used to with Groovy 1.0. I get a security exception. If I double click on "groovyc.bat" it works. Here is the error and my environment variable setting. Any idea of what's going on?

Thanks

Fred

It is illegal to have rt.jar on your CLASSPATH (it contains classes that
begin with "java.lang").

Thanks Jim. I removed rt.jar from the classpath and it works now.

Is it an issue for just for Groovy or any java program in general?

Cheers

Any Java. To define classes in the "java.lang" package you have to use
the -Xbootclasspath option of the java executable.

Actually I mean to say defining classes in any package beginning "java.".
