'Illegal UTF8 string in constant pool in class file error in IntelliJ

Whenever I try to run a file (java main, cucumber feature, junit test) I get the following error in IntelliJ Idea:

I tried restarting the IDE, importing the project again but nothing worked. Did anyone experience this error before ?

javaintellij-idea


Solution 1:[1]

I have managed to fix this by deleting .IntelliJIdea folder and reimporting the project.

Solution 2:[2]

Adding this answer for those who also experience this issue not only in IntelliJ but also with maven builds outside IntelliJ. Reinstalling the JDK was the only solution that worked for me.
