EXCEPTION_MAP

private static final Map<Integer,BiFunction<String,Integer,MeosException>> EXCEPTION_MAP

LAST_ERROR

private static final ThreadLocal<int[]> LAST_ERROR

The last error MEOS reported to the calling thread, as {code, level}.

MEOS raises an error on the thread that made the call and keeps its own error number in thread-local storage, so this mirror is per-thread too. One slot shared across threads lets a thread consume or clear an error raised on another, which loses the exception its caller was owed and hands it to whichever thread asks next.
