[ERROR] /Users/jake/Projects/Minecraft/PaperMC/test.java:3:12: Variable 'local' should be declared final. [FinalLocalVariable]
Audit done.
Checkstyle ends with 1 errors.The param local variable in the static method inside the Test interface should be reported as needing the final modifier which, if I'm understanding the documentation correctly, adding the PARAMETER_DEF token to the FinalLocalVariable check should do.
If I change Test to a class instead of interface, it correctly reports both, so I'm guessing someone just forgot about methods inside of interfaces.
