Whatever works for you. Although JMeter 2.3.4 will run with Java 1.4, it will generally run better with Java 1.5 or later. > when you ask for stack trace do you mean the output of jmeter.log...?

In this case, however, the NPE is not the original cause of the problem, it's only a symptom, so the full jmeter log is needed.
