Description of the change:
See #733 (comment)
Motivation for the change:
Enables the creation of match expressions that evaluate the JFR event types available on a given target JVM. This probably isn't very useful for Stored Credentials, but for Automated Rules it will couple well with #733 , as well as with custom application-level JFR events. It becomes possible to define Automated Rules that use a preset or custom event template containing framework- or application-level events, and only activate on targets where those event types are actually present. For example, a Rule can be created that matches Quarkus applications which have the
quarkus-jfrextension enabled.How to manually test:
./smoketest.bash -Oquarkus-jfrextension, so if these two PRs are combined then the Quarkus-specific events referenced in that comment can be used. Otherwise, an event type ID likejdk.CPULoadcan be used to test the expression evaluation.
