Description Mark Drilling 2005-06-02 01:13:11 UTC
I get the following exception on the remote clients when running multiple 
remote clients in non-Gui mode:
java.lang.NullPointerException
  at org.apache.jorphan.collections.HashTree.traverseInto(HashTree.java:1012)
  at org.apache.jorphan.collections.HashTree.traverse(HashTree.java:990)
  at org.apache.jmeter.engine.StandardJMeterEngine.run
(StandardJMeterEngine.java:330)
  at java.lang.Thread.run(Unknown Source)

Im using the JDBC sampler.  Here is the command line -
jmeter -n -r -Jremote_hosts=client1,client2 -tC:\in.jmx -lC:\out.jtl

Does this also happen with other samplers, e.g. the JavaTest sampler?

Does it happen straight away, or only after the test has started running?

Any messages in the console windows (apart from JVM garbage collection info)?

I havent tried with other samplers.  I can run multiple remote clients 
successfully from the GUI - but when I run the same case from command line, I 
get this error.
It happens right away.  I get the exception on the remote client and the 
controlling process hangs.  Nothing else of interest is in the remote logs or 
console.  I am attaching the host jmeter.log - there is a different exception.

I have a similar problem.  Just testing whether I can add additional 
information.

I am also two problems when when running multiple remote clients in non-Gui 
mode.  My command line (have also tried through Ant which has same problems):
java -jar ApacheJMeter.jar -n -r -
p //Ct38i/shared/AutoTest/Jmeter/bin/jmeter.properties -d C:/jakarta-jmeter-
2.1.1 -t //Ct38i/shared/AutoTest/Jmeter/AntLoadTest.jmx -
l //Ct38i/shared/AutoTest/results_template/JMeterResults.jtl -
JtestId=ES1_W1_T1 -Jrequest.threads=3 -Jrequest.loop=4 -
Jrequest.plan=ES1control.bsh -Jrequest.testPlanDir=//Ct38i/shared/AutoTest/

Problem 1.  The test case uses the parameters but the parameters are not 
passed to the remote machine.  

Problem 2.  The test runs successfully (the log and results output is as 
expected). However, the test hangs.  My output is:
Created the tree successfully
Configuring remote engine for 150.151.223.196
Starting remote engines
Remote engines have been started
Tidying up ...
... end of run

Trying to use JBuilder to step through the JMeter code so will let u know if I 
find anything.
Cheers

Seems to be same as other remote engine crashes
