Too many classes (interned strings).

Caused by memory Meter plugin

'Memory Meter' plugin <http://plugins.netbeans.org/plugin/5664/memory-monitor> is causing OOME in NetBeans after it is installed. The JDK example you are using has the following code:

    // Test thread to consume memory
    static class Memeater extends ClassLoader implements Runnable {
        Object y[];
        public Memeater() {}
        @Override
        public void run() {
            y = new Object[10000000];
            int k =0;
            while(true) {
                 if (k == 5000000) k=0;
                 y[k++] = new Object();
                 try {
                     Thread.sleep(20);
                 } catch (Exception x){}

                 // to consume perm gen storage
                 try {
                     // the classes are small so we load 10 at a time
                     for (int i=0; i<10; i++) {
                        loadNext();
                     }
                 } catch (ClassNotFoundException x) {
                   // ignore exception
                 }

           }

        }
}

This thread eats memory and perm gen. So anybody, who installs this plugin will get OOME in NetBeans in a few minutes. Please remove the plugin from plugin center until this is fixed.
