                 URL: https://issues.apache.org/jira/browse/GROOVY-8875
             Project: Groovy
          Issue Type: Bug
            Reporter: Pruteanu Dragos
             Fix For: 3.x


Hi,

I execute this. The third shell.evaluate throws an exception:

final GroovyShell shell = new GroovyShell( binding, FormsGroovyConfiguration.CONFIG );
// THIS WILL FORCE NULL VARIABLES TO PRINT AS '' INSTEAD OF NULL
// http://stackoverflow.com/questions/10517817/how-to-get-rid-of-null-when-concating-string-in-groovy
shell.evaluate("org.codehaus.groovy.runtime.NullObject.metaClass.toString = \{return ''}");

 

And got the next exception. This used to work in Java 10 and before, it crashes under Java 11. Could have something to do with java modules ?
