Paul King commented on GROOVY-9904:
-----------------------------------
{{DefaultGroovyMethods.size(StringBuffer)}} was deprecated almost 9 years ago
and hasn't been one of the available extension methods since that time. Perhaps
you really meant to use the {{StringGroovyMethods}} version which still works?
In fact the {{CharSequence}} variant is the one available as an extension
method. If you just use the extension method from Groovy, you never have to
worry about such changes, e.g. {{new StringBuffer('test').size()}}.
> DefaultGroovyMethods.size() breaking change in 3.0.x
