Ecilpse Java Builder Crashes

Ecilpse Java Builder Crashes

I have been using this Eclipse installation for over a year now. Suddenly, the builder began to fail. I have not changed any settings. The only thing that could create this situation is Eclipse, which suffered a lot, and then the developer began to create these NPEs ...

Can someone help me figure out how to make the builder work again?

I thought about it a few hours later, hitting my head.

Eclipse crashed when I was in the middle of writing code. So the code that existed when you restarted Eclipse looked something like this ...

public abstract class AbstractAmbassadorQueueTask implements AmbassadorQueueTask{

    // BEGIN: This is where I was working when Eclipse crashed.
    private static SessionListenerIfc l = new SessionListenerAdapter(){

    } // <<< **Note the missing semicolon after the last brace.**
    // END: This is where I was working when Eclipse crashed.

    public AbstractAmbassadorQueueTask() {
        super();
    }
}
