Disables the use of biased locking. Some apps with considerable quantities of uncontended synchronization could achieve significant speedups with this flag enabled, but programs with sure patterns of locking may even see slowdowns. .

Sets the size in bytes with the code section made up of profiled techniques. This flag is applied provided that —XX:SegmentedCodeCache is enabled.

Don’t convert off verification due to the fact this lowers the security provided by Java and will trigger issues because of unwell-shaped class files.

-Xms6m If you don’t established this selection, then the First measurement is set as the sum of your measurements allotted for that outdated era plus the young technology. The Preliminary dimensions of your heap with the younger technology may be set using the -Xmn solution or even the -XX:NewSize alternative.

-Xmn268435456 Rather than the -Xmn option to set both the initial and highest dimensions of your heap for that youthful technology, You should use -XX:NewSize to established the First dimensions and -XX:MaxNewSize to set the maximum size.

Converts an angle calculated in degrees to an around equivalent angle measured in radians. The conversion from degrees to radians is usually inexact.

Home windows: The following illustration shows tips on how to established the heap dump file to C:/log/java/java_heapdump.log:

Autotunes RTM locking according to the abort ratio. This ratio is specified because of the -XX:RTMAbortRatio possibility. If the amount of aborted transactions exceeds the abort ratio, then the strategy that contains the lock is deoptimized and read this recompiled with all locks as typical locks. This option is disabled by default. The -XX:+UseRTMLocking selection must be enabled.

0 In the event the argument is below zero. Unique Circumstances: In case the argument is NaN, then the result is NaN. In case the argument is optimistic zero or negative zero, then the result is similar to the argument.

Allows the dumping on the Java heap to your file in The present Listing by using the heap Discover More Here profiler (HPROF) each time a java.lang.OutOfMemoryError exception is thrown.

Permits invoking of concurrent GC by utilizing the Method.gc() request Home Page and unloading of classes through the concurrent GC cycle. This feature is disabled by default and might be enabled only together with the -XX:+UseConcMarkSweepGC possibility.

PI The double benefit that is definitely closer than another to pi, the ratio of your circumference of a circle to its diameter.

Sets a custom made command or possibly a series of semicolon-separated instructions to run when an OutOfMemoryError exception is initial thrown. When the string contains Areas, then it need to be enclosed in quotation marks. For an example of a command string, see The outline on the -XX:OnError alternative.

Specifies a command to perform on a way. For example, to exclude the indexOf() means of the String class from remaining compiled, use the following:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
