The JSR-01 release obviously broke all backwards compatibility and requires effectively any Groovy script to be rewritten. But JSR-01 is not the final word, and planned changes in subsequent releases will break your code again :-) Also keep in mind that the migration page only points out the well-known changes. When they switched from the hand-coded parser to the ANTLR based one they also introduced many small differences that will bite various people over time. Most of them are subtle whitespace differences but there are a few others as well. Get ready to keep migrating those scripts over and over again.
