If running with -Djdk.instrument.traceUsage or > -Djdk.instrument.traceUsage=true, the calls to the Instrumentation API print a > trace message and stack trace. I believe the flag should mention that what is traced is just the dynamic instrumentation, static instrumentation is not an issue, perhaps "-Djdk.instrument.traceDynamicUsage=true" Rémi
