What Does This Do

Turns off the automatic enablement of the ddprof profiler for J9 versions of JDK 11.0.18 and JDK 17.0.6

Motivation

There is a bug in then J9 JVMTI implementation causing JVM to crash when a jmethodId of a method that was recently unloaded is used. According to the specification the JVMTI must be resilient to such calls and store the minimal info necessary to describe the method even if the class is unloaded.
