-XX:CompileOnly=java.lang.String::duration,java.util.Checklist::size Though wildcards aren’t supported, it is possible to specify only the class or package deal title to compile all strategies in that course or deal, and specify just the strategy to compile methods using this identify in any course:
By default, this selection see this website is disabled and also the collector is picked out mechanically dependant on the configuration with the machine and kind from the JVM. If it’s enabled, then the -XX:+UseParallelOldGC choice is instantly enabled, Except you explicitly disable it.
Specifies the title of The category to become released. Command-line entries next classname are definitely the arguments for the main approach.
