Description

@Singleton(lazy=true) does not perform the correct double checked locking for Java

It does the naive version where no local variable is declared.

More info here: http://groovy.329449.n5.nabble.com/Singleton-double-checked-locking-fix-td4302467.html

I have a patch that I will commit.
