Paul King resolved GROOVY-9409.
-------------------------------
    Fix Version/s: 3.0.2
                   4.0.0-alpha-1
                   2.5.10
         Assignee: Paul King
       Resolution: Fixed

The behavior for our use hasn't changed since it broke JDK8 when I tried but there is now an overloaded constructor that you could use to use different parsing options for your use case.

But as Jochen alluded to, this is treated as mainly an internal class which in fact won't work under JDK11 anyway. We are likely to deprecate and remove this class at some point. In our current planning it won't be needed for internal use by Groovy 4 when we are all indy code based.
