Detecting stacktrace image - IllegalStateException: Timeout4 TIMEOUT

I interrupt the rendering thread, when an user requests a different diagram while rendering. It used to work fine, or maybe it still does in some cases, but sometimes it returns this image: https://imgur.com/a/LxmZSJ2

There is no way to detect if it is an stacktrace image or what. Description returned from `SourceStringReader#outputImage` contains only: "(0 entities)".

It would be nice if the Description contained the exception instance or even the whole text, so I can just ignore that image - not cache it, and properly log/report the exception.

Also it seems to me that it should not be a TIMEOUT.

This could probably be fixed: https://github.com/plantuml/plantuml/blob/2c655a6b7481c39a41fc0dc57b561bd1db1ecfe2/src/net/sourceforge/plantuml/cucadiagram/dot/ProcessRunner.java#L73-L87

So to sum it up, there are 2 issues

- not being able to detect the stacktrace error image

- incorrect timeout detection due to InterruptedException
