That is a commercial aspect that needs you to also specify the -XX:+UnlockCommercialFeatures option as follows:
Enables the dumping on the Java heap to the file in The existing Listing by utilizing the heap profiler (HPROF) whenever a java.lang.OutOfMemoryError exception is thrown.
Sets the file to which verbose GC activities information and facts must be redirected for logging. The data penned to this file is analogous on the output of -verbose:gc With all the time elapsed due to the fact the first GC event previous each logged party. The -Xloggc possibility overrides -verbose:gc if both equally are provided Using the exact same java command.
Logs messages tagged Using the gc tag using the trace degree into a rotating file set with 5 files with measurement one MB with The bottom identify gctrace.txt and works by using decorations uptimemillis and pid.
Passes a JIT compilation choice to the required strategy rather than the last argument (possibility). The compilation choice is set at the top, soon after the method title.

This can make it easy to disable assertions in all lessons aside from process lessons. The -disablesystemassertions possibility enables you to disable assertions in all procedure classes.
Sets the utmost code cache sizing (in bytes) for JIT-compiled code. Append the letter k or K to indicate kilobytes, m or M to point megabytes, or g or G to indicate gigabytes. The default maximum code cache measurement is 240 MB; for those who disable tiered compilation with the option -XX:-TieredCompilation, then the default size is forty eight MB.
Specifies the utmost measurement (in bytes) of the data chunks within you can try these out a recording. Append k or K, to specify the dimensions in KB, or m or M to specify the scale in MB, or g or G to specify the size in GB. By default, the most dimensions of data chunks is ready to 12 MB.
Loads the desired indigenous agent library. Following the library name, a comma-separated list of alternatives unique into the library can be utilized.
Contents while in the argument documents are expanded for the reason that usually, they would be specified to the command line until the -Xdisable-@data files option was encountered.
