Description Matthias Garzke CLA 2020-04-30 05:50:14 EDT 
Hi together, 

I'm a beginner in using Microcontrollers and want to explore the whole spectrum of possibilities.
Unfortunately i encountered a problem lately when it comes to debugging.

I'm currently using a new STM32F407 Discovery Board and the latest eclipse 2020 version.

When i try to start debugging, a window shows up with the following message:

An internal error occurred during: "Launching stm32f4-test Debug".
org.eclipse.debug.internal.core.StreamsProxy.<init>(Ljava/lang/Process;Ljava/lang/String;)V

I can show you the latest log-file entry of the .metadata folder:

!MESSAGE An internal error occurred during: "Launching stm32f072b-disco-test Debug".
!STACK 0
java.lang.NoSuchMethodError: org.eclipse.debug.internal.core.StreamsProxy.<init>(Ljava/lang/Process;Ljava/lang/String;)V

	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63)


As you can see, I am using the ac6 workbench. Also I am using the SPL  Library, since i began to learn with it and it seems a little more intuitive for me.

I tried to completely reinstall eclipse, but this did not solve the problem.
Please excuse me, if i'm missing informations.
I hope that anyone could help me with this problem since i'm despairing.
Thanks in advance!

fr.ac6.mcu.debug.openocd.processanalyzer.logger.OpenOCDRuntimeProcess.createStreamsProxy(OpenOCDRuntimeProcess.java:268) uses internal API that is changed via bug 558489.

Whoever provides fr.ac6.mcu.debug.openocd.processanalyzer should update the code and do not use internal API.

@Paul: would it make sense to provide old StreamsProxy(Process process, String encoding) constructor that re-directs to the new one StreamsProxy(Process process, Charset encoding)?

Yes. Would not hurt us to restore the method. I'll make a patch.

Thanks for the quick response and effort!

Is there any action needed to be done by myself?

Have you found the code for the client? If it uses even more internal API?

Find out the code for that tool or find out the authors and ask if the proposed patch makes their code happy again. Google just found this: https://www.openstm32.org/forumthread8134 for me.

No, that's why I restored all three constructors changed in bug 558489. If it breaks on other internal api changes, well there is a known risk on using internals.

The product is probably this [1] but I found no code and apart from the forum thread you linked only this related thread [2] which describes the same error Matthias posted.

If this may helps you:

This is the source from where i obtain the workbench.
