Description of problem:

I have a simple groovy file with

println System.getProperty("java.class.path")

If I run it with groovy, it runs as expected. If I try to compile with groovyc, it has an exception.


Version-Release number of selected component (if applicable):
groovy-1.8.9-7


Steps to Reproduce:
1. echo 'println System.getProperty("java.class.path")' > info.groovy
2. groovy info.groovy
3. groovyc info.groovy

Actual results:
$ groovy info.groovy 
/usr/share/java/ant.jar:/usr/share/java/ant/ant-junit.jar:/usr/share/java/ant-launcher.jar:/usr/share/java/antlr.jar:/usr/share/java/objectweb-asm/asm.jar:/usr/share/java/objectweb-asm/asm-analysis.jar:/usr/shar

However, groovyc chokes on it:

$ groovyc info.groovy                                                                                                                                                         [19/472]

Expected results:
groovyc should compile this.
