Description
Customers use Java Web Start for large applications for a while already.
 Support for garbage collection algorithms is restricted to the Serial 
 Collector and the ConcurrentLowPause Collector (CMS).

 There was a limited set of GC options available in the list of supported 
 java-vm-args of the j2se element:
 http://download.oracle.com/javase/6/docs/technotes/guides/javaws/developersguide/syntax.html#jnlp

 This list was recently considerably enhanced:

 CR# 6953324 (RFE)
 Please add more options to the list of secure jnlp properties
 Implemented in Java SE 6 Update 23

 Unfortunately, support for prominent garbage collection algorithms
 was not regarded in CR# 6953324.

 This request is to increase the list of supported options again with the 
 following ones:

-XX:[+,-]UseParallelOldGC
-XX:[+,-]UseParallelOldGCCompacting

-XX:[+,-]UseParallelGC
-XX:GCTimeLimit
-XX:GCHeapFreeLimit
-XX:[+,-]UseGCTimeLimit
-XX:[+,-]UseGCOverheadLimit
-XX:[+,-]ScavengeBeforeFullGC

-XX:[+,-]UseParallelScavenge

will add this request with other requests for expansion of secure vm-args and properties in JDK9 as per http://ccc.us.oracle.com/7024585, adding the following secure vm-args: -XstartOnFirstThread -XX:+UseG1GC -XX:+UseStringDeduplication -XX:+PrintStringDeduplicationStatistics -XX:[+,-]UseParallelOldGC -XX:[+,-]UseParallelOldGCCompacting -XX:[+,-]UseParallelGC -XX:[+,-]UseGCTimeLimit -XX:[+,-]UseGCOverheadLimit -XX:[+,-]ScavengeBeforeFullGC -XX:[+,-]UseParallelScavenge and the following secure vm-arg prefixes: -XX:StringDeduplicationAgeThreshold -XX:GCTimeLimit -XX:GCHeapFreeLimit and closing JDK-8078230 and JDK-8129750 as dupes of this bug.
