What steps will reproduce the problem?
1. I've tarred up the whole directory structure.  Go to the test/ subdir
2. java -jar ../../xruby/xruby-0.1.0.jar tc_rexml.rb
3. BOOM!

Exception in thread "main" java.lang.NullPointerException

What is the expected output? What do you see instead?

Expect to produce a .jar


What version of the product are you using? On what operating system?

Mac OS X:
java version "1.5.0_06"

Thank you Tim.

I have no problem to (at least) compile the code you provided on Windows (tried 
both 
trunk and 0.1.0):

>java -jar ..\xruby-0.1.0.jar -c tc_rexml.rb
Added tc_rexml/test_compare$1.class
Added tc_rexml/initialize$3.class
Added tc_rexml/doctype$4.class
Added tc_rexml/cdata$5.class
Added tc_rexml/comment$6.class
Added tc_rexml/instruction$7.class
Added tc_rexml/tag_end$8.class
Added tc_rexml/tag_start$9.class
Added tc_rexml/BLOCK$11.class
Added tc_rexml/text$10.class
Added tc_rexml/report$12.class
Added tc_rexml/main.class
Generated tc_rexml.jar

My OS is:
>java -version
java version "1.5.0_09"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_09-b03)
Java HotSpot(TM) Client VM (build 1.5.0_09-b03, mixed mode)

Right now none of our developers owns OSX, but we will try Linux to see if it 
is 
reproducible.

Tried on an OSX system and tc_rexml.rb compiles OK. I think Tim misspelled the 
name 
of the file.

I will keep this issue open until XRuby is able to run rexml.
