[java] Cannot start the Java LS in debug mode

[kittaakos]

I got this when starting the server with DEBUG_MODE = true.

ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [debugInit.c:750]

One has to change the order of the arguments. It seems, the debug mode has never worked before:

if (debug) {
    args.push('-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=1044');
}

args.push(...[
    '-Declipse.application=org.eclipse.jdt.ls.core.id1',
    '-Dosgi.bundles.defaultStartLevel=4',
    '-Declipse.product=org.eclipse.jdt.ls.core.product'
]);

if (debug) {
    args.push('-Dlog.level=ALL');
}

Edit: updated the snippet.
