The decompiler was not wise enough to handle some statements, most likely compiled try-catch-statements. So he resigns, and does something syntactically correct, but unlikely to be like this is the original source.

goto _L1

is just a Java statement meaning go to the instruction AFTER the block of code following the goto statement (This is mad, I know, but that is how Java implemented it).

Open editor, write something else. Use different decompiler. – Daniel Mar 14 '11 at 15:07

goto isn't a Java keyword. What you're seeing is a remnant of improper decompilation.

Strictly speaking `goto` **is** a keyword in Java. It just has no meaning. – Joachim Sauer Mar 14 '11 at 14:40
Well, the code never compiles if there's a `goto`. Quoting Sun, "The keywords const and goto are reserved, even though they are not currently used." it is a reserved keyword. – adarshr Mar 14 '11 at 14:44
