Hello,Please review the changes to fix JDK-8180334, essentially -DJAVA_ARGS exceeds
a Visual Studio C++ compiler limit, and this fix provides a way to specify very long string literals, by the build system.
This also includes some minor and subtle simplifications and cleanups wrt. the JAVA_ARGS and its handling. Thanks Webrev: http://cr.openjdk.java.net/~ksrini/8180334/webrev.00 JBS: https://bugs.openjdk.java.net/browse/JDK-8180334
