No. It would be like finding a memory unsafe caused bug in a Java application that is due to a bug in the JRE. That would absolutely warrant a title like “I found memory unsafe bug in my Java code” when everyone expects Java code to be memory safe, which is analogous to the article in question.
I do not think you are completely grasping what you are talking about (what is a 'memory unsafe bug'?). Even in the example you give, that title would be literally wrong, as there will be no bug in your Java code; there would be a bug in the execution due to a deviation in the runtime executing your program.
