Paul King updated GROOVY-10643:
-------------------------------
    Description: 
*{color:#DE350B}Addendum{color}*: it seems like the protected method {{}}

A change in Groovy 3 (see GROOVY-9380 for details) was to consolidate classes 
from the legacy Java5 through Java7 classes into Java8. Those classes are part 
of Groovy's plugin mechanism and aren't meant to be used directly. The legacy 
classes were deprecated in Groovy 3 and removed in Groovy 4. This was an 
intended breaking change for anyone using those classes directly. Remember the 
change is transparent for anyone using the plugin mechanism as intended. A 
subset of those classes are also directly called by the bytecode for Groovy 2.5 
compiled code with Indy enabled, i.e. were part of the Groovy runtime for that 
version. Removing backwards compatibility for those classes was unintended.

This would mostly impact folks who might create applications from a mixture of 
dependencies, e.g. maybe a helper classes, library or plugin compiled under 
Groovy 2.5 with Indy enabled and then used in conjunction with another 
application compiled under Groovy 4. This will be fixed in the next point 
release.
