Option and Default Value Description
-XX:+UseG1GC Use the Garbage First (G1) Collector
-XX:MaxGCPauseMillis=n Sets a target for the maximum GC pause time. This is a soft goal, and the JVM will make its best effort to achieve it.
-XX:InitiatingHeapOccupancyPercent=n Percentage of the (entire) heap occupancy to start a concurrent GC cycle. It is used by GCs that trigger a concurrent GC cycle based on the occupancy of the entire heap, not just one of the generations (e.g., G1). A value of 0 denotes 'do constant GC cycles'. The default value is 45.
-XX:NewRatio=n Ratio of old/new generation sizes. The default value is 2.
-XX:SurvivorRatio=n Ratio of eden/survivor space size. The default value is 8.
-XX:MaxTenuringThreshold=n Maximum value for tenuring threshold. The default value is 15.
-XX:ParallelGCThreads=n Sets the number of threads used during parallel phases of the garbage collectors. The default value varies with the platform on which the JVM is running.
-XX:ConcGCThreads=n Number of threads concurrent gar

Option and Default Value Description
-XX:-AllowUserSignalHandlers Do not complain if the application installs signal handlers. (Relevant to Solaris and Linux only.)
-XX:AltStackSize=16384 Alternate signal stack size (in Kbytes). (Relevant to Solaris only, removed from 5.0.)
-XX:-DisableExplicitGC By default calls to System.gc() are enabled (-XX:-DisableExplicitGC). Use -XX:+DisableExplicitGC to disable calls to System.gc(). Note that the JVM still performs garbage collection when necessary.
-XX:+FailOverToOldVerifier Fail over to old verifier when the new type checker fails. (Introduced in 6.)
-XX:+HandlePromotionFailure The youngest generation collection does not require a guarantee of full promotion of all live objects. (Introduced in 1.4.2 update 11) [5.0 and earlier: false.]
-XX:+MaxFDLimit Bump the number of file descriptors to max. (Relevant to Solaris only.)
-XX:PreBlockSpin=10 Spin count variable for use with -XX:+UseSpinning. Controls the maximum spin iterations allowed before entering operating sys

We can make this file beautiful and searchable if this error is corrected: It looks like row 2 should actually have 1 column, instead of 2. in line 1.
