Hi,

I am using Java 1.6 and executed the JXTables packColumns only to find
that the UI is hanging. I use JGoodies so not sure if that is related
but how can I troubleshoot this? If I run in debug and get the
stacktrace this is what I find - UIDefaults hung after issuing a
'wait' command

In javax.swing.UIDefaults this is the code:

        /* If the LazyValue for key is being constructed by another
         * thread then wait and then return the new value, otherwise
drop
         * the lock and construct the ActiveValue or the LazyValue.
         * We use the special value PENDING to mark LazyValues that
         * are being constructed.
         */
        synchronized(this) {
            value = super.get(key);
            if (value == PENDING) {
                do {
                    try {
                        this.wait(); <<<<<<<=====
Hung here
                    }
                    catch (InterruptedException e) {
                    }
                    value = super.get(key);
                }
                while(value == PENDING);
                return value;
            }
            else if (value instanceof LazyValue) {
                super.put(key, PENDING);
            }
            else if (!(value instanceof ActiveValue)) {
                return value;
            }
        }
