Description Martin Krauskopf 2008-07-14 20:59:11 UTC

It happens to me after I start to debug NetBeans in NetBeans and then in debuggee run the Ruby app. Let me know, if the
stacktrace is not enough to detect the culprit, and you need more info.

Inlining, it's short:

java.lang.ClassCastException: com.sun.tools.jdi.ThreadGroupReferenceImpl cannot be cast to com.sun.jdi.ThreadReference

Comment 1 Martin Krauskopf 2008-07-14 21:20:50 UTC

Actually it happens every time I start a Ruby application. Reproduced always by:

(in the debuggee)
1) Create new Ruby application
2) Press <S-F6>
