John Wagenleitner closed GROOVY-7790.
-------------------------------------
Resolution: Not A Problem
Since the [GDK
docs|http://docs.groovy-lang.org/latest/html/groovy-jdk/java/util/Map.html#get(java.lang.Object,%20java.lang.Object)]
specify {{defaultValue}} as
{quote}
the value to return and add to the map for this key if there is no entry for
the given key
{quote}
It looks like your results match what is specified. If we are missing
something, please reopen and let us know. Thanks.
