Logs all messages by utilizing the infolevel to stdout with uptime, concentrations, and tags decorations. This is certainly akin to employing:
Returns the floating-issue amount adjacent to the 1st argument during the path of the 2nd argument. If each arguments Review as equivalent a price similar to the second argument is returned. Particular instances: If either argument is often a NaN, then NaN is returned. If both equally arguments are signed zeros, a worth similar to route is returned. If start off is ±Float.MIN_VALUE and course has a value this kind of that The end result should have a lesser magnitude, then a zero With all the exact sign as start out is returned.

This ratio is applied if the -XX:+UseRTMDeopt possibility is enabled. The default value of this feature is fifty. Which means the compiled code is deoptimized if fifty% of all transactions are aborted.
Note that from the old logging, PrintReferenceGC had an effect provided that PrintGCDetails was also enabled.
Displays Edition information and facts then exits. This selection is akin to the -showversion choice other than which the latter doesn’t instruct the JVM to exit following displaying Edition facts.
