Hi,
What kind of JDK are you using?
Here are the links[1][2][3] of groovy unit test.

[1]https://svn.apache.org/repos/asf/camel/trunk/components/camel-script/src/test/java/org/apache/camel/builder/script/GroovyScriptRouteTest.java
[2]https://svn.apache.org/repos/asf/camel/trunk/components/camel-script/src/test/java/org/apache/camel/builder/script/example/GroovyFilterTest.java
[3]https://svn.apache.org/repos/asf/camel/trunk/components/camel-script/src/test/resources/org/apache/camel/builder/script/example/groovyFilter.xml
