Description

The GroovyConsole AST browser doesn't use the same classloader for the AST BRowser.

1. Open groovyConsole and import a JAR using the Script menu item.
2. Write a script that uses something out of that JAR
3. Open AST Browser
4. AST browser will show a ClassNodeFOund exception for anything out of the JAR

I suspect that the classes are being loaded into the classloader GroovyConsole uses to execute the script but not the classloader used to execute AST Browser.

Hi Hamlet, attaching a patch here for review. Let me know if it seems ok. I have tested from UI with the steps you provided in the JIRA.

This patch looks good... I just have one change I would make:

The classLoader parameter/field in ScriptToTreeNodeAdapter is optional... and then there is a block 

        if(!classLoader) {
            // AstBrowser has been launched independently and not from groovy console 
            classLoader = new GroovyClassLoader()
        }

I would prefer classLoader to be a final field and a required parameter, then it is up to the calling clients to specify the correct classloader. This way there is not a null value floating around the codebase. It is best to drive null out of our programs.
