Please, review a fix for: https://bugs.openjdk.java.net/browse/JDK-8165276
CSR draft (one CSR reviewer is needed before finalizing it): https://bugs.openjdk.java.net/browse/JDK-8248189 Webrev: http://cr.openjdk.java.net/~sspitsyn/webrevs/2020/instr-setAccessible.1/ The java.lang.instrument spec: https://docs.oracle.com/en/java/javase/14/docs/api/java.instrument/java/lang/instrument/package-summary.html Summary: The java.lang.instrument spec clearly states: "The agent class must implement a public static premain method similar in principle to the main application entry point." Current implementation of sun/instrument/InstrumentationImpl.java allows the premain method be non-public which violates the spec. This fix aligns the implementation with the spec. Testing: A mach5 run of jdk_instrument tests is in progress. Thanks, Serguei
