What does the jsr keyword mean?

Question

I\'m looking at some Java code, and I\'ve noticed the following:

if (!foo(bar, baz, qux)) {
    i = 0; jsr 433;
}

javac chokes on it, sayin

Answer 1

I'm close to sure that this code is coming from a Java decompiler.

The JSR 432 smells like a decompiler note, where the decompiler found a "jump" code but doesn't have a clue on how to express it in java language.
