Subject A question about synchronization in Derby
Date Fri, 15 Dec 2006 16:30:16 GMT
Today, when I read the source code of 

I found some synchronized code like:

public boolean isDirty()    {

    synchronized (this)  {

        return isDirty || preDirty;



public boolean isActuallyDirty() {

    synchronized (this) {

        return isDirty;



I have two questions about them, hope someone can answer me:

1. Is it necessary to synchronize the code in these places?

2. I saw someone else commented on some code (in derby) said it's not

    good to return from inside of a synchronized block. What potential 

    it will cause if return from inside of a synchronized block?
