[Issue]: Error with JMeter 5.6.2 in connection with plugin kloadgen 5.6.5 #412
Comments
Thank you for collaborating with the project by giving us feedback! In case it applies, it would be helpful if you could attach an example AVRO and an example test plan for us to reproduce the error. Cheers! |
HI @xck1007 , |
Unfortunately, because of the errors above, I cannot work with kloadgen 5.6.5. Besides the errors above, I get a nullpointer exception when loading the key from the schema registry (Field "Key Subject Name" => Button "Load Subject"). An ex-colleague of mine had fixed kloadgen_5.1.2 for jmeter 5.5 so that I could use it. I am adding the fixed version of kloadgen here. As I am not a developer, I am not able to do this like my ex-colleague. I have to switch to JMETER 5.6.2 for security reasons and would like to continue using kloadgen. |
Sorry, the fixed Version of kloadgen_5.1.2 was to big |
I also have these errors with kloadgen 5.6.7 and jmeter 5.6.2. |
HI @xck1007 , Had you the opportunity to try the latest released version? Cheers |
Hi, II have downloaded jmeter version 5.6.2 from the Apache website and kloadgen version 5.6.7 from here (https://mvnrepository.com/artifact/com.sngular/kloadgen/5.6.7) again. When I start jmeter 5.6.2 without kloadgen, I get no errors. If I then place kloadgen 5.6.7 in the lib/ext directory, I get the errors described above again. I can't imagine that the error should only occur for me. I am using Java version 11.0.10. |
I have downloaded the jar-version from https://mvnrepository.com/artifact/com.sngular/kloadgen/5.6.7. |
Hi @xck1007, |
I also see these errors on my Linux VM with Java 17. |
Hi @xck1007 I tried your jmx, just replacing with one our testing schemas and disabling your variable generator in my local system and did not get any of those errors. |
Hi, I have now recreated this on my private laptop by installing oracle java jdk 17 and jmeter 5.6.2 on it. Then I loaded kloadgen 5.6.7 from the maven repo (https://mvnrepository.com/artifact/com.sngular/kloadgen/5.6.7) and copied the kloadgen-jar file into the jmeter directory lib/ext. After starting JMeter via jmeter.bat I got the error message again. I am not using any plugins at the moment. I am surprised that you are not experiencing these errors. I have not been able to get it to run without errors on several laptops and operating systems. If I delete the kloadgen plugin, jmeter starts without errors. Cheers |
Hi @xck1007 , Never see something like that, we are using a mix of Mac and Windows systems to work. I also tried in my personal Linux systems and always worked as a charm. I recall see those errors when people where trying compilation for Jmeter 5.5 on 5.6.2 Jmeter installations. Cheers |
Hi, i use jmeter 5.6.2/kloadgen 5.6.7 on Windows 10 and ubuntu 22.04 with java 17. it is a mystery to me. Maybe you have dependencys that I don't have? Thank you very much for your help :-) Cheers |
Hi, no we usually develop with plain JMeter and no other plugins installed. My only concern is may be the deliverable is not build correctly. Mostly of the people who use the plugin build it from the source code. I'm go to investigate this a bit more further. Can you try to download the code and build it ? Cheers |
Hi, i am not a java developer. But I can give it a try. But I can't do it that quickly because I'll be on holiday too. Cheers |
Hi, no problem no rush, I'll investigate in the mean time. Cheers |
Hi, the deliverable 5.6.7 is not build correctly. I downloaded the code and build it. I no longer see the errors :-) thanks p.s. now i have a problem with the schema registry config element. For this will open a new issue. ERROR c.s.k.p.e.SchemaRegistryConfigPropertyEditor: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 502 cannotconnect" |
What happened?
When I use the kloadgen plugin 5.6.5, I see exceptions (IncompatibleClassChangeError) in the jmeter log file after starting jmeter 5.6.2. I haven't used any function of kloadgen until then. I have tested with java 11 and java 17. I see these exceptions also with JMeter 5.5 and kloadgen 5.6.5.
I expect, that after starting JMeter 5.6.2 with kloadgen 5.6.5 there are no exceptions.
KloadGen Version
5.6.5
