JVM should have exited but did not

Question

While executing script using JMeter in non gui mode i'm getting error message described below when Thread group count is 100 and ramp up period is 60 sec

Tidying up ...    
The JVM should have exitted but did not.
The following non-daemon threads are still running (DestroyJavaVM is OK):

How to resolve this error? what exactly this error means? How to handle this error?

This is a bug fixed in jmeter 3.1 (to be released soon):

• https://bz.apache.org/bugzilla/show_bug.cgi?id=60053

Report generation is in progress while you have this message.

Wait for it to be generated and kill the jvm instance:

kill pid
