I was just typing the code below. Position caret after the dot before the semicolon. Press Ctrl-Space to see code completion options. Type "get(" - in my case the text after the dot changes to "equals(in)" which is quite annoying. This is not the only code that leads to such misbehavior. Happens to me relatively frequently, about ten times a day.

package org.netbeans.core.startup;

import java.util.concurrent.CountDownLatch;
import org.openide.util.lookup.ServiceProvider;

@ServiceProvider(service=Runnable.class, path="WarmUp")
public class WarmUpSupportTask implements Runnable {
    @Override
    public void run() {
        int timeOut = Integer.getInteger("warmup.delay", -1);
        if (timeOut > 0) {
            ClassLoader l = Thread.currentThread().getContextClassLoader();
            Class<?> c = l.loadClass(WarmUpSupportTest.class.getName());
            CountDownLatch in = c.getDeclaredField("in").;
        }
    }
}
