Hi,
when trying to start JMeter 1.8 (using JDK 1.3.1 on
Linux), I get the following error:
java.lang.reflect.InvocationTargetException:
java.lang.UnsupportedClassVersionError:

This seems to imply that I'm running the wrong JDK
version. I'm using:
/home/rgasch/jakarta-jmeter/bin> java -version
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition
(build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed
mode)
which seems to be a rather recent version. Do I really
need JDK 1.4 or does this point at some other problem?
Thanks/Greetings
