NPE from o.j.r.scope.ManyVarsDynamicScope#getValue
--------------------------------------------------
Key: JRUBY-2444
URL: http://jira.codehaus.org/browse/JRUBY-2444
Project: JRuby
Issue Type: Bug
Components: Interpreter
Affects Versions: JRuby 1.1.2
Environment: [EMAIL PROTECTED]:~$ jruby -v
ruby 1.8.6 (2008-04-25 rev 6555) [i386-jruby1.1.1]
Reporter: Martin Krauskopf
Priority: Blocker
Might be bug in jruby-debug-base, but very likely in JRuby as well. It should
not thrown such NPE. Having JRuby trunk and jruby-debug-base trunk (tester.rb
is one-liner):
