RE: Thread Sinchronization
Hi,
Can you provide a bit more of your code so I can get a better understanding
of what you are trying to do? I don't understand where the boolean is being
set or where it is being checked.
Cheers,
John

Yes I have. But it didn't help.
Volatile modifier works on jvm cacheing issues isnt it?
Thanks Neale.

I'm developing a new assertion listener.
it calculates the average of the sample times that arrive on*
AssertionResult getResult(SampleResult) *method. Depending on the
average time, it does something or not.
When the average time reaches the defined value a boolean is set to
true, but the other threads take some delay to realize this happened and
continue for a while.
For example:
If at the 5 delivered sampleResult the specified value was reached, it
continues until all remaining threads realize that.
The method seems something like:
*public AssertionResult getResult(SampleResult response) {
calculate(response); // calculate the average. this is a synchronized
method if( ! averageReached ){ //do somethings }
return assertionResult;
}
*
I tried to synchronize the methods which set the boolean value. Tried to
synchronize the whole getResult method. Tried to insert some
Thread.delay() at the top. But still got no lucky.
The boolean value is a static field.
Any ideas are welcome.
Thanks
