--------------------------------------------
Key: JRUBY-1701
URL: http://jira.codehaus.org/browse/JRUBY-1701
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Reporter: Charles Oliver Nutter
Assignee: Marcin Mielżyński
Seems to be a problem with this code causing NPE in rbx mspec run:
>From RubyRegexp.regsub:
{noformat}
case '+':
if (regs == null && mbeg == -1) {
no = 0;
continue;
} else {
no = regs.numRegs-1;
while(regs.beg[no] == -1 && no > 0) no--;
if (no == 0) continue;
}
break;
{noformat}
And the trace:
{noformat}
Exception in thread "main" java.lang.NullPointerException
