Research direction

Start with me.konloch.kontainer.io.DiskReader.loadAsString at DiskReader.java:61 and the call from KrakatauDisassembler.decompileClassNode at KrakatauDisassembler.java:99. Reproduce the reported Windows 10 failure using the supplied Java, Bytecode Viewer, and Python versions, then trace why the temporary .j path cannot be read. Done means the reported Krakatau decompilation failure is resolved and the relevant path can be opened successfully.
