Description

Wondering if this bug is new in Groovy 1.8.4; it seems it work better in 1.8.2.

The problem is that groovysh is throwing IncompatibleClassChangeError in a few cases:
import com.not.Found // import that doesn't resolve to class
show // command doesn't run at all
purge // command doesn't run at all

Groovy 1.8.4 appears to be working well, otherwise.

Please let me know if you need further info. It seems reproducible, here.

Thanks!
John

Hi,

I would just like to confirm that I am seeing the same.

1.8.2 seems to work.

Thanks,
Serge

I think this is related to GROOVY-4838. Jdk 7 added a protected constructor to the Exception class. For Groovy 1.8.4, it works for me if I use jdk7 to run groovysh but I get the IncompatibleClassChangeError if I run with jdk6. 

~/java/groovy-1.8.4$ bin/groovysh 
Groovy Shell (1.8.4, JVM: 1.7.0_02)
Type 'help' or '\h' for help.

My guess this is happening because org.codehaus.groovy.tools.shell.CommandException is a Groovy class and v1.8.4 was compiled with jdk7.

If I build from source using jdk7, then I get the IncompatibleClassChangeError when running groovysh with jdk6. Same occurs when building using jdk6 and running with jdk7.
