Hi and thanks for your input.
Please provide more details -

• JVM vendor and version used to run the attacher jar
• JVM vendor and version used to run the Java application you are trying to attach to
• the exact command line and options you use for running the attacher

Thanks.

Hi ，My problem has been solved after that I changed my jvm to oracle JDK (java version "1.8.0_101").
but the public support in https://www.elastic.co/guide/en/apm/agent/java/current/supported-technologies-details.html said open JDK 8 is supported, made me confused.

[Eyal_Koren]

You are absolutely right, this is a source of confusion. The page you referenced is about what JVMs we work on properly, so if you used the javaagent option, it would definitely be expected to work.

We still need to figure out where it works and where it doesn't, and whether there is something we can do where it does not, which is part of the reason this setup option has the disclaimer This installation method is experimental.

Thanks a lot for your valuable input!
