I am trying to run jconsole on my Mac OSX machine to try to analyze some memory leak problems in the application.
jconsole really appears, and it lists local processes, but when I try to connect to a local process, the connection just disconnects.
I found good troubleshooting advice here: https://blogs.oracle.com/jmxetc/entry/troubleshooting_connection_problems_in_jconsole
although most of the links on this page no longer work. After reading this article, I started jconsole with this command and saw that jconsole actually throws an exception when trying to connect to my local process.
jconsole -J-Djava.security.debug = all 2> & 1 | tee / temp / log.txt
I see this exception trace, which I will add to the end of this question, but my question is “what can I do to fix this”? This mac was inherited from another developer who has just left, and I really would like to try and not reinstall the OS. Here is the exception, and I hope that any answer to this question will help someone else:
