Matching with a wildcard selects all tag sets that contain at least the desired tags. With no wildcard, only actual matches of the specified tag sets are selected.

Executes a application encapsulated within a JAR file. The filename argument is the title of a JAR file which has a manifest that contains a line in the form Primary-Class:classname that defines The category with the public static void principal(String[] args) process that serves as your application's place to begin.

Sets the Place (in bytes) allotted to your long lasting technology that triggers a rubbish selection if it’s exceeded. This option was deprecated in JDK 8 and superseded by the -XX:MetaspaceSize alternative.

Enables splitting the verification process. By default, this feature was enabled from the prior releases, and verification was break up into two phases: sort referencing (executed from the compiler) and kind examining (executed by the JVM runtime). Verification is now break up by default and not using a strategy to disable it.

This can be a professional function that needs you to definitely also specify the -XX:+UnlockCommercialFeatures choice. This is often also an experimental function; it could alter in foreseeable future releases.

Sets The trail and file title to the place log data is written. By default, the file is made in the current Performing directory, and it’s named hotspot.log.

Sets the size in bytes on the code section containing profiled strategies. This flag is used only if —XX:SegmentedCodeCache is enabled.

Sets the Java thread stack dimension (in kilobytes). Use of a scaling suffix, including k, ends in the scaling with the kilobytes price so that -XX:ThreadStackSize=1k sets the Java thread stack sizing to 1024*1024 bytes or one megabyte. The default worth depends on the System:

Permits logging of compilation activity to some file named hotspot.log in the current Doing work directory. You may specify a distinct log file route and identify using the -XX:LogFile alternative.

Sets the thread stack measurement (in bytes). Append the letter k or K to indicate KB, m or M to point MB, or g or G to indicate GB. The default worth relies on the System:

The equipment like jcmd, jinfo, jmap, and jstack shipped Together with the JDK aren’t supported when using the equipment from a person JDK Edition to troubleshoot a distinct you could try this out JDK Model.

Logs messages tagged with at least gc, class, and heap tags using the trace stage to stdout but only log messages tagged with meta with level. The default configuration for all other messages at the extent warning is in influence except for People that include threads.

Sets the value in the quit-the-entire world (STW) worker threads. This feature sets the worth of threads to the number of logical processors. The worth of threads is the same as the amount of rational processors up to a price of 8.

The flags have now been manufactured out of date, and their use generates a warning. In a long run launch these flags will try this web-site be eliminated entirely.
