switch/case Indentation

execute java reuses Skript’s own config-node parser to read the block, and that parser treats any line ending in : as opening a nested section — including Java’s case 1: / default:.

That means case labels must sit at the same indentation as the switch statement itself, one level shallower than normal Java style, with only the body indented further:

switch (x) {
case 1:
    result = "one";
    break;
default:
    result = "other";
}

Indenting case/default one level deeper — the way an IDE would format it — makes Skript’s parser report an indentation error, and the plugin rejects the block with maintain the script's indentation.
