StackOverflowError caused by non-compiling superclass recursion in source code

[Firestar99]

StackOverflowError occurs when typing source code and a "superclass recursion" is typed, see example below.

class Buffer extends Buffer {

}

Of course very rare to actually happen, but you may want to create an (optionally inner) class Buffer and have it extend my.project.Buffer by first typing Buffer and then autocompleting the fully qualified name, in that short moment before autocompleting the IDE complains about the Plugin crashing. It's just reporting that the plugin crashed and you experience a short lag spike but otherwise does not disrupt your work much if at all.

Thought I'd still report it even if the impact is very little :) Like your plugin!

I fixed, please retest. The "Cyclic inheritance involving" is an error but during editing this may occur.
Thank you for the detailed bug report
