Specifies the RTM abort ratio is specified being a share (%) of all executed RTM transactions. If many aborted transactions turns into higher than this ratio, then the compiled code is deoptimized.
The -disableassertions (-da) possibility relates to all course loaders and also to technique lessons (which don’t have a category loader).

String deduplication reduces the memory footprint of String objects around the Java heap by Benefiting from the fact that a lot of String objects are equivalent. Instead of each String item pointing to its personal character array, identical String objects can point to and share the same character array.
Windows: The next instance shows how the -XX:OnError option may be used to run the userdump.exe utility to obtain a crash dump in the event of an irrecoverable error (the %p designates The existing method).
