Description

org.codehaus.groovy.runtime.DefaultGroovyMethods.size(StringBuffer sb) 

doesn't have the same behavior between 2.5.x and 3.0.x

assert org.codehaus.groovy.runtime.DefaultGroovyMethods.size(new StringBuffer('test')) == 4 // true in 2.5.x
assert org.codehaus.groovy.runtime.DefaultGroovyMethods.size(new StringBuffer('test')) == 4 // false in 3.0.x, expected 1

I didn't find any explanation about this change in the release note.
