Hello,

I ran into the same error which got fixed by installing the latest java version from http://www.oracle.com/technetwork/java/javase/downloads/jdk10-downloads-4416644.html, click on jdk-10.0.1_windows-x64_bin.exe. I also updated the environment variables with the location of the new java version. Prior to this I had updated my JMeter Plugins Manager from the JMeter GUI.

Hope this helps.
