WIP: New Processor - Pull Request
Hey,
I just created a new pull request for my work in progress: I am currently working on new processors that are similar to the existing BooleanTimer and BooleanCounter in streampipes.processors.transformation.jvm.processor, but support string values. However, I am running into the following bug, when adding the StringTimerController to the TransformationJvmInit file and can't make sense of it.
15:44:43.523 SP [XNIO-1 task-26] ERROR io.undertow.request - UT005023: Exception handling request to /
javax.servlet.ServletException: java.lang.NullPointerException: inStream parameter is null
at org.glassfish.jersey.servlet.WebComponent.serviceImpl(WebComponent.java:408)
at org.glassfish.jersey.servlet.WebComponent.service(WebComponent.java:346)
It should work as the codebase is simply borrowed from the existing _BooleanTimer_. I double-checked names, id's, etc. but I am afraid I am unable to identify the root cause.
Any help is appreciated!
Kind regards,
Felix

Hi Dominik,
I just recreated everything from scratch and for some mysterious, unknown reason the bug is gone. Thank you for your help!

Hi Dominik,
I removed the blank space as you suggested and created a new pull request! I'm afraid the bug still persists despite fixing the blank spaces.
Thank you!!

Hi Felix,
thanks a lot! These are really cool processors.
I'm not sure if this is related to your bug, but when I merged your pull request, I couldn't pull the project properly on windows as some folder names in the resources folder seem to contain a blank space:
https://github.com/Madabaru/incubator-streampipes-extensions/tree/dev/streampipes-processors-transformation-jvm/src/main/resources/org.apache.streampipes.processors.transformation.jvm.stringoperator.timer%20
(see the %20 at the end)
I reverted your pull request afterwards so that I could checkout the project again - can you please check if there is a blank space, remove it and create a new pull request?
Maybe this could also be related to your error, if not, I'll be happy to checkout the code and help you finding the issue!
Dominik
