Mandy, thank you for the suggestion. I'll retarget the bug and CSR to jdk 17 as nobody is objecting. Also, wanted to make it clear about Exception messages that are provided for two different cases. The test java/lang/instrument/NonPublicPremainAgent.java defines a non-public premain method: ` static void premain(String agentArgs, Instrumentation inst) {` With the m.canAccess check the following message is provided (it looks right): ` Exception in thread "main" java.lang.IllegalAccessException: method NonPublicPremainAgent.premain must be declared public ` Without this check the message was (not sure, it is good enough): ` Exception in thread "main" java.lang.IllegalAccessException: class sun.instrument.InstrumentationImpl (in module java.instrument) cannot access a member of class NonPublicPremainAgent with modifiers "static"` Also, I've added a new test java/lang/instrument/NonPublicAgent.java which defines a non-public agent class with a public premain method. With the m.canAccess check the following message is provided (it does not look right): ` Exception in thread "main" java.lang.IllegalAccessException: method NonPublicPremainAgent.premain must be declared public ` Without this check the message is (it looks pretty confusing): ` Exception in thread "main" java.lang.IllegalAccessException: class sun.instrument.InstrumentationImpl (in module java.instrument) cannot access a member of class NonPublicAgent with modifiers "public static"` So, it seems we also need an explicit check for agent class being public with a right message provided. Please, let me know what you think. I've done some tests refactoring motivated by some private requests from Mandy. Will publish the update as soon as it is ready. Hopefully, today. ------------- PR: https://git.openjdk.java.net/jdk/pull/1694
