This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
This is an example of deadlock, But I can't understand where is the deadlock in that code?
The deadlock happened when two thread want to access one resource, But I don't such thing in that coe
I think your definition of deadlock is incorrect. There are actually many ways to deadlock, and the example is defining it as and showing as... A deadlock can occur when two threads are trying to grab two different locks. They each grab one of the locks, and then wait for the other lock. In this case, the deadlock is occuring because neither can grab the other lock because it is owned by the other thread -- and neither will release the lock that they did grab because they are both in a wait state waiting for the other lock. This condition can't be resolved, hence, deadlock.
But I didn't see any link to download this add on....
and don't find that on Netbeans....
I also try SendSignal in cmd....But unlucky....I don't know how to find the ID of process that is belongs to program that I run .....
I want to see thread dump. What is the simplest way?

e. Race conditions
Two processes might share control or data. Race conditions is
the term applied to compromising this sharing, which typically
results from synchronization errors, when the potential exists
for process conflicts, and a resulting vulnerability. A typical
exploit interrupts a pair of sequential calls that are meant to be
performed automatically without interruption by another
thread or process on the machine with a third process.
One example is the combined checking of access rights to a
file, followed by a subsequent call to write or read that file. By
interrupting the process between the two calls, an attacker can
rewrite or modify the file because this behavior is expected.
The attacker can place inappropriate information into a file,
or perhaps access an inappropriate file
May someone explain more about the example?
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
