> This is the implementation for JEP 451. There are two parts to this: > > 1. A multi-line warning is printed when a JVM TI or Java agent is loaded into > a running VM. For JVM TI, the message is printed to stderr from > JvmtiAgent::load. For Java agents, it is printed to System.err (as that may > be redirected) in the JPLIS (j.l.instrumentation) implementation. This part > includes an update to the JVM TI spec and API docs to require the warning. > > 2. If running with -Djdk.instrument.traceUsage or > -Djdk.instrument.traceUsage=true, the calls to the Instrumentation API print > a trace message and stack trace. > > Testing: tier1-6
