Summary: NullPointerException on loading script
Product: JMeter
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P3
Component: Main
AssignedTo: [email protected]
ReportedBy: [email protected]

I am facing a problem which appeared after my colleague updated one of our
scripts. He saved the script with the jmeter revision 1077948
I am able to load and execute my script without any problems if I do it from
the GUI without providing it in the command line. However if I pass the script
in the command line I get the following exception:
2010/09/20 17:12:09 ERROR - jmeter.engine.StandardJMeterEngine: Uncaught
exception: java.lang.NullPointerException
at org.apache.jorphan.collections.HashTree.traverseInto(HashTree.java:989)

The problem seems to be in Iterator<?> iter = list().iterator();
while (iter.hasNext()) {
Object item = iter.next();
final HashTree treeItem = getTree(item);
visitor.addNode(item, treeItem);
treeItem.traverseInto(visitor);
}
I don't understand how this problem can even happen. What occurs is that
treeItem is null.
Adding some expressions evaluation I got the following results:
list().contains(item) => true
containsKey(item) => false
get(item) != null => false
I noticed that in the script that no longer works some elements are saved
differently than they used to be:
This is how it used to work:
<org.apache.jmeter.protocol.smtp.sampler.SmtpSampler
guiclass="org.apache.jmeter.protocol.smtp.sampler.gui.SmtpSamplerGui"
testclass="org.apache.jmeter.protocol.smtp.sampler.SmtpSampler" testname="SMTP
1" enabled="true">
This is how it is now:
<SmtpSampler guiclass="SmtpSamplerGui" testclass="SmtpSampler"
testname="SMTP 1" enabled="true">
However I do not know if this is the cause of the problem...
Any light in this matter would be very appreciated.
