Hi, Currently the jfr (Flight Recorder) feature is being built by default for Zero JVMs. However, it's not clear whether there will be jfr support for the Zero variant JVM. At this point, when StartFlightRecording option is being used for a Zero JVM it asserts/crashes. It seems more appropriate to disable the feature for a default build and require one to enable the feature explicitly via:
configure --with-jvm-feature=jfr --with-jvm-variants=zero We can revisit this change of default once there is good Zero+JFR support, which currently isn't the case. Bug: https://bugs.openjdk.java.net/browse/JDK-8203410 webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8203410/webrev.01/ Testing: Verified that the StartFlightRecording option is unrecognized for a default --with-jvm-variants=zero build. Thoughts? Thanks, Severin
