require 'tmpdir' fails when embedded in a java app that has messed with the
classpath
-------------------------------------------------------------------------------------
Key: JRUBY-3809
URL: http://jira.codehaus.org/browse/JRUBY-3809
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.3.1
Environment: OS X 10.5.7, Java 5, BSF
Reporter: Adam Murray
Assignee: Thomas E Enebo
Priority: Minor
I'm not sure exactly what the containing Java app is doing to the classpath,
because this works fine in a simple test app I put together, but when I try to
run
require 'tmpdir'
in my embedded app, it failes with IOError -- tmpdir
The problem line is
require 'Win32API'
in tmpdir.rb
Turning on $DEBUG=true I got the following stack trace:
java.lang.StringIndexOutOfBoundsException: String index out of range: 0
at java.lang.String.charAt(String.java:558)

I have no idea why this is happening in my environment, and I can't reproduce
it for a test case, but it seems easy enough to fix that
StringIndexOutOfBoundsException. I forked JRuby to play around with it and will
submit a patch if I get something working.
