title: jmeter on macos stuck launching GUI
body: <p>I am using latest <code>JMeter 5.2.1</code> on <code>Mojave 10.14.6</code>, I have both Java 8 and Java 11. I was able to use JMeter a few weeks ago and no idea why but it won't load the GUI. I look at <code>jmeter.log</code> and no errors it just looks something like this:</p>

  <p>after a few seconds it shows in activity manager that the process is unable to respond. I have tried uninstalling it and reinstalling it, restarting, checkout out source code from git and building it with gradle, installing another Java 8 and 11 from adoptopenjdk. Any way to debug this? logs have no error so not sure what else. Annoying thing is it worked like 2 weeks ago and I havent done anything with JMeter since. </p>
  
  <p>Also, tried older JMeter versions 5.0 and 3.3 with both java 11 and 8, had various errors indicating it wouldn't work, so I went back to the latest versions.</p>
  
  <p>Also, I was for some reason, not able to install using <code>brew install jmeter --with-plugins</code>, I think maybe it's because I updated brew awhile ago but not sure.. just keeps saying with plugin invalid options. </p>
