IDE freeze with invalid source code causing superclass recursion #32

Open Firestar99 opened 3 years ago

Firestar99 commented 3 years ago

Complete IDE freeze when typing source code and a "superclass recursion" is typed (see example below) and one would right-click -> Show Object Layout. Happened while testing for #29. However as it is invalid source code and noone would actually do this action in normal use feel free to just ignore :)

class Buffer extends Buffer {

thank you for the report, I don't think it worth to fix it due to low possibility of the bug. I'll leave this ticket open and maybe someday I'll fix it
