Description:
Using the following insert of code;
void myfunc() {
synchronize (myobject) {
...
}
}
Obviously, if you fail to instantiate myobject, it does not
have a instance of an object to lock on. However, if you
do forget to instantiate a locking object, it will not
throw an exception at runtime. It will allow the lock to
occur, lock and run the code in the synchronized area,
and will not release the lock, thus hanging all code
which synchronizes on this object. Obviously, this is a
bug in the java application, however, the runtime system
should throw an exception when you try to synchronize on
a null object.
