        Description

        FULL PRODUCT VERSION :
        java version "1.8.0_40"
        Java(TM) SE Runtime Environment (build 1.8.0_40-b25)
        Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

        javac -version
        javac 1.8.0_40


        ADDITIONAL OS VERSION INFORMATION :
        Linux 3.16.7-ckt5-sk+ #1 SMP Tue Feb 17 22:00:49 EST 2015 x86_64 x86_64 x86_64 GNU/Linux

        A DESCRIPTION OF THE PROBLEM :
        When performing a particular set of specific operations when initializing a `static final` field, javac overflows the stack.

        It appears as if the combination of String append and performing a map operation on a stream cause this behavior.

        Behavior noticed by user on reddit forum (not me, although I have reproduced it): https://www.reddit.com/r/learnprogramming/comments/32bfle/can_you_explain_this_strange_java8_error/

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        Attempt to compile provided source code.

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        Successful compilation
        ACTUAL -
        The system is out of resources.

        CUSTOMER SUBMITTED WORKAROUND :
        From forum post:

        "Oh and additionally, if you put the stream/map/collect calls into a random static function and call that instead, it all works fine. It just dislikes being directly attached to the static final field."
