Variable exception after modifying bytecode

[1470429149]

This is very strange. I changed iconst_0 of a certain row to iconst_1, but a strange prompt appeared when running

java.lang.ClassFormatError: Duplicated LocalVariableTable attribute entry for 'e' in class file net/playavalon/mythicdungeons/dungeons/Instance

MythicDungeons2.zip

[1470429149]

I used the following startup parameters C:\Users\Administrator\Desktop\bash\jdk-22.0.1+8\bin\java -jar recaf-launcher-0.4.1.jar auto

This got fixed in d07739627c5482320d17cc67cfccbec4a253c275 unintentionally. Editing the methods and checking the javap outputs no longer shows duplicate e entries in the local var table.
