-----------------------------------------------------------------
Key: JRUBY-2824
URL: http://jira.codehaus.org/browse/JRUBY-2824
Project: JRuby
Issue Type: Bug
Environment: Latest JRuby 1.1.3 (almost released one) :)
Reporter: Vladimir Sizikov
Assignee: Thomas E Enebo
Priority: Blocker
Fix For: JRuby 1.1.3
In our best tradition, here's a blocker with JRuby crash in interpreter, right
before the release ;)
Essentially, the following code:
{noformat}
if ()
end
{noformat}
or
{noformat}
while ()
end
{noformat}
crash JRuby interpreter:
{noformat}
jruby -X-C -e "if (); end"
Exception in thread "main" java.lang.NullPointerException
