Same issue on Windows 10; Tweak mode shows the above message, and doesn't work.

Same issue on MacOS Mojave 10.14.3 with Processing 3.5.3

It won't run the program and gives this error:

java.lang.ClassCastException: processing.app.RunnerListenerEdtAdapter cannot be cast to processing.mode.java.JavaEditor
at processing.mode.java.JavaMode.handleTweak(JavaMode.java:145)
at processing.mode.java.JavaEditor.lambda$0(JavaEditor.java:1101)
at java.lang.Thread.run(Thread.java:748)

[KorySchneider]

Same issue on Windows 10 Processing 3.5.3 and Ubuntu 16 Processing 3.5.3.

Error message from Windows 10:

java.lang.ClassCastException: processing.app.RunnerListenerEdtAdapter cannot be cast to processing.mode.java.JavaEditor
	at processing.mode.java.JavaMode.handleTweak(JavaMode.java:145)
	at processing.mode.java.JavaEditor.lambda$0(JavaEditor.java:1101)
	at java.lang.Thread.run(Thread.java:748)

Reinstalled 3.4, it is working in that release.

Seems that this is caused by this change. Reverting that makes tweak mode work, but it seems that there was a good reason for the change and a revert would cause other problems.

@JakubValtar what do you think of @dzaima's guess that #5486 broke Tweak mode? Do you think it would be possible for someone to fix Tweak mode given the changes in 5486, or is the mode not possible going forward, and should it be removed or not install?

[KorySchneider]

Would be a shame to remove the tweak mode, it can be very useful in certain contexts.

I've fixed tweak mode on my branch off of sampottingers Java 11 work here. The fix for Processing 3 should be pretty much the same, but I'm having trouble testing because of the Oracle Java self-downloading problem. It might have trouble with threads & synchronization and probably isn't the best solution, but it works for me ¯\_(ツ)_/¯

Same problem here (Win10 64-bit), same error:
