JRuby 1.7.5 doesn't compile valid class files #1136
Description
I'm hoping this isn't a warbler-based bug, but given the stack trace, I'm assuming it has more to do with the JRuby 1.7.5 compiler.
Under 1.7.4 bundle exec warble jar:clean gemjar compiled runnable jar will create a properly runnable jar file.
Under 1.7.5, a jar-file will be created, but upon running it, the following exception will be raised:
-> % java -jar smb-full.jar -T
Exception in thread "main" java.lang.ClassFormatError: Extra bytes at the end of class file JarMain

Looks like this issue might be the underlying reason for the exception.
FWIW, using:
-> % java -version
java version "1.7.0_40"
OpenJDK Runtime Environment (IcedTea 2.4.1) (suse-8.18.1-x86_64)
