-XX:CompileCommand=exclude,*.indexOf The commas and intervals are aliases for spaces, rendering it easier to go compiler instructions via a shell. You'll be able to go arguments to -XX:CompileCommand working with Areas as separators by enclosing the argument in quotation marks:Loads the required indigenous agent library. Following the library identify, a comma-divided listing of possibilities certain to the library can be used.
Disables using biased locking. Some apps with sizeable quantities of uncontended synchronization may perhaps attain important speedups with this flag enabled, While programs with certain patterns of locking may even see slowdowns.
Allows invoking of concurrent GC by using the Procedure.gc() ask for and unloading of classes in the course of the concurrent GC cycle. This selection is disabled by default and can be enabled only along with the -XX:+UseConcMarkSweepGC selection.
Sets the scale in the allocated class metadata Area that should cause a rubbish selection The 1st time it is exceeded. This threshold for just a garbage assortment is elevated or lowered according to the volume of metadata utilized. The default measurement relies on the platform.
The worth on the -cp parameter will be the frequent class path prefix shared with the Hi and Hi applications.
Sets the length of time (in milliseconds) a softly reachable object is retained active over the heap after the previous time it absolutely was referenced. The default price is a person next of lifetime per free of charge megabyte while in the heap. The -XX:SoftRefLRUPolicyMSPerMB choice accepts integer values symbolizing milliseconds for every a single megabyte of the present heap dimensions (for Java HotSpot Shopper VM) or the maximum probable heap measurement (for Java HotSpot Server VM).
