What Does This Do
Implements and registers an
EndpointCheckpointerwhich doesn't use JFR to record the endpoint events required for endpoint profiling to work. This means endpoint profiling can be used on non-OpenJDK JVMs such as J9. This is simple glue code for a component which is well tested across a range of architectures/libc/JDK distributions in the java-profiler repository, so no new tests beyond the existing smoke tests are added.Motivation
