Description

# jirb
irb(main):001:0> JRUBY_VERSION
=> "1.1.6"
irb(main):001:0> "\222".unpack('m')
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -110
	at org.jruby.util.Pack.unpack(Pack.java:902)
	at org.jruby.RubyString.unpack(RubyString.java:3835)

org/jruby/util/Pack.java: problem is that safeGet() returns a signed byte, and uses that as index into b64_xtable.. negative index => ArrayIndexOutOfBoundsException

Can you try this on a nightly build? I think it may be fixed. http://jruby.headius.com:8080/hudson under jruby-dist.
