            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 system thread synchronization code. (Introduced in 1.4.2.)

            
              -XX:-RelaxAccessControlCheck
              Relax the access control checks in the verifier. (Introduced in 6.)

            
              -XX:+ScavengeBeforeFullGC
              Do young generation GC prior to a full GC. (Introduced in 1.4.1.)

            
              -XX:+UseAltSigs
              Use alternate signals instead of SIGUSR1 and SIGUSR2 for VM internal signals. (Introduced in 1.3.1 update 9, 1.4.1. Relevant to Solaris only.)

            
              -XX:+UseBoundThreads
              Bind user level threads to kernel threads. (Relevant to Solaris only.)

            
              -XX:-UseConcMarkSweepGC
              Use concurrent mark-sweep collection for the old generation. (Introduced in 1.4.1)

            
              -XX:+UseGCOverheadLimit
              Use a policy that limits the proportion of the VM's time that is spent in GC before an OutOfMemory error is thrown. (Introduced in 6.)

            
              -XX:+UseLWPSynchronization
              Use LWP-based instead of thread based synchronization. (Introduced in 1.4.0. Relevant to Solaris only.)

            
              -XX:-UseParallelGC
              Use parallel garbage collection for scavenges. (Introduced in 1.4.1)

            
              -XX:-UseParallelOldGC
              Use parallel garbage collection for the full collections. Enabling this option automatically sets -XX:+UseParallelGC. (Introduced in 5.0 update 6.)

            
              -XX:-UseSerialGC
              Use serial garbage collection. (Introduced in 5.0.)

            
              -XX:-UseSpinning
              Enable naive spinning on Java monitor before entering operating system thread synchronizaton code. (Relevant to 1.4.2 and 5.0 only.) [1.4.2, multi-processor Windows platforms: true]

            
              -XX:+UseTLAB
              Use thread-local object allocation (Introduced in 1.4.0, known as UseTLE prior to that.) [1.4.2 and earlier, x86 or with -client: false]

            
              -XX:+UseSplitVerifier
              Use the new type checker with StackMapTable attributes. (Introduced in 5.0.)[5.0: false]

            
              -XX:+UseThreadPriorities
              Use native thread priorities.

            
              -XX:+UseVMInterruptibleIO
              Thread interrupt before or with EINTR for I/O operations results in OS_INTRPT. (Introduced in 6. Relevant to Solaris only.)
