Description

GroovyClassLoader fails with NullPointerException if java.class.path system property contains a path that includes .jar file that has no Class-Path attribute in it's Manifest file.

In the expandClassPath, line 249, null may be returned, which then gets passed to expandClassPath as third parameter. Attempt to call 'split' on it causes NPE:

java.lang.NullPointerException
