Issue:

We are running Jmeter scripts in ASM but they keep failing with errors

Non HTTP response code: java.lang.NullPointerException

Environment:
App Synthetic Monitor 8.5
Cause:

Currently ASM script monitors do not support jmx scripts that have been created in JMeter 3.0

Resolution:

1.  Download the Jmeter script from the affected monitor in ASM

2.  Open the downloaded script in Jmeter 2.1.x and resave it

3.  Upload the newly saved script to the affected monitor in ASM

Additional Information:

This issue will be addressed initially by informing the user that Jmeter 3.0 scripts are currently not supported and ultimately by adding that support in a future release.
