Yes I did (of course ;)) I did not get a chance to have another look yet, still planned...

OK, so we've ruled out an AST I think.  Dumb question, but did you recompile GroovyUtil.java after changing the Groovy versions?  Because it is compiled against Groovy and maybe something was changed between versions.

You are welcome Jacopo,

Being (almost) in vacation, I did not find the time to explain how we use Groovy, thanks!

I hope to have another look before Monday...

Jacques, Cédric, Keegan.

I apologize if I jump in this conversation but I am interested in this issue reported by Jacques and I would like to share more information about how the code is used in OFBiz.

The GroovyBaseScript.groovy [*] is in the classpath, and here is how we use it (I have simplified the code for readability):

CompilerConfiguration conf = new CompilerConfiguration();
GroovyClassLoader groovyClassLoader = new GroovyClassLoader(GroovyUtil.class.getClassLoader(), conf);

Then we use "groovyClassLoader" to parse our scripts with something like this:

groovyClassLoader.parseClass(UtilIO.readString(in), location);

Kind regards,


[*] You can review the content of GroovyBaseScript.groovy here:

FYI, it is possible to apply ASTs to scripts.  Remember that at the end of the day, scripts are compiled too (just compiled on the fly).  How are you extending org.ofbiz.service.engine.GroovyBaseScript?  Is it in a jar on the classpath?  And are you sure there are no ASTs in it?

Since we don't compile groovy code I think we don't do AST transformations.

Are you writing your own AST transformations? If so, it is likely a bug in one of them, and the error message is there to tell you something is wrong with it.

We heavily rely on Groovy in Apache OFBiz where it replaced BeanShell 7 years ago. We only use it for scripts, we don't use the compiler.

I thought upgrading from 2.2.1 to 2.4.4 would be a breeze. So I simply deleted groovy-all-2.2.1.jar and added groovy-all-2.4.4.jar locally before committing. But I was surprised to get this error, which exists in all our scripts.

I looked for similar cases on the Internet and found

So do you think this could be a bug in Groovy or should we rather dive in in our code?
