Jmeter - java exception while clicking on response in View Results Tree

Question

I'm facing this issue: Once a test plan has completed, if there are errors, when I click on the red row, I got this exception in the log:

Answer 1

I believe this may be an issue with Jmeter not yet supporting Java 10. This was a similar issue that was reported against Jmeter 3.x without support for Java 9 Bug 61529. I would suggest trying to run with Java 9 and then I believe you will avoid this issue.
