This permits code on course route that relies on using setAccessible to break into JDK internals, or to do other unlawful accessibility on associates of classes in these packages, to operate as per previous releases. This enables the two static entry (such as, by compiled bytecode) and deep reflective obtain.
-XX:CompileOnly=java.lang.String::length,java.util.Listing::dimensions Whilst wildcards aren’t supported, you can specify only The category or offer identify to compile all solutions in that class or package deal, as well as specify just the tactic to compile techniques using this name in any class:
