[GROOVY-3711] NPE when using JSR223 implementation under some conditions

• Type: Bug

Description

Example:

import java.lang.*

This causes:

...
Caused by: javax.script.ScriptException
	at org.codehaus.groovy.jsr223.GroovyScriptEngineImpl.eval(GroovyScriptEngineImpl.java:306)
	at org.codehaus.groovy.jsr223.GroovyScriptEngineImpl.eval(GroovyScriptEngineImpl.java:113)
	... 92 more
Caused by: java.lang.NullPointerException
	at org.codehaus.groovy.jsr223.GroovyScriptEngineImpl.eval(GroovyScriptEngineImpl.java:253)

The reason is that GroovyScriptEngineImpl.getScriptClass() returns null in this case (I tried to understand why but couldn't).
Since it's null the eval() method fails at line 253.

Note that there was another error hiding this error, this time caused by livetribe, which is now fixed in livetribe 2.0.6. You can see more information here:
