I'm not being facetious. I don't know anything about the implementation of the JVM or its byte-code, and was hoping to learn a bit. But...

1. How was I supposed to know 0x19 was the relevant byte to look at? I know there should be a load opcode somewhere, how do I know it was that 0x19?

2. What's going on between the load opcode, and the actual string data about 120 bytes apart?

3. Is looking up the definition of an opcode from a list really a mnemonic device?

Maybe that last bit was a bit facetious.
