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."
