Are you using some sort of ThreadPoolExecutor such as the ones provided by java.util.concurrent.Executors class? Perhaps you are facing a case of tasks being finished by silently uncaught exceptions. The dump fragment looks like an inactive pooled thread and one reason to get an inactive thread (which should be active) is an exception throwed up but surrounded by the default thread pool implementation.
It means that the TASK which the THREAD were executing finished (abruptaly or not) and now the thread is waiting for another task to execute (see java.util.concurrent.ThreadPoolExecutor openjdk source):
Another (most) probable cause is an uncaught exception thrown during the task execution. Within a thread pool, an unchecked exception like this will abruptaly stop the method execution and (surprisely) be swallowed into a java.util.concurrent.FutureTask object. In order to avoid things like this, I use the following idiom:
First, a really dumb question, I was just wondering what the waiting 'parking' means ? Is the thread waiting to be parked or is it just been parked and therefore is in wait state ? And when that parking happen, how much cpu/memory resources are taken ? What's the purpose of parking a thread ?
A parking system is a convenient, safe, and environmentally sustainable method that solves a major chunk of the traffic management issue. A well-designed parking system can reduce traffic flow, effectively utilize space, generate revenue, and give an enhanced user experience.
Define three static variables: totalSlots, availableSlots, and parkedCars. totalSlots represents the total number of parking spaces, while availableSlots keeps track of how many remain free. parkedCars is an ArrayList that stores the license plate numbers of the cars currently parked.
Define the main() method and create an object of the Scanner class. Ask the user to enter the total number of parking slots and store it in totalSlots. Initially, the available slots equal the total slots so initialize availableSlots to the same value as totalSlots.
On running the code above, the program asks to enter the facility's total number of parking slots. On entering 5, it gives the option to park a car, remove it, view all the parked cars, and exit the program. On choosing option 1, it asks to enter the car's license plate number and decreases an available slot by parking it.

A parking garage charges a $2.00 minimum fee to park for up to three hours.
The garage charges an additional $0.50 per hour for each hour or part thereof in excess of three hours.
The maximum charge for any given 24 hour period is $10.00.
Assume that no car parks for longer than 24 hours at a time.
Write a Java program that calculates and displays the parking charges for each customer who parked in the garage yesterday.
Input the number of hours parked for each customer. The number of customers can be fixed using a final constant.
One of the most prominent questions asked in a Java interview is the parking lot design in Java. Parking lot design in Java is a design problem that deals with how the vehicles are parked in a parking lot. It is mainly asked in the HLD or LLD (High Level or Low-Level Design) round of the top multinational companies such as Amazon, Google, Facebook, etc. Note that there is no right or wrong answer to this design problem. Therefore, such type of design problem requires a good discussion with the interviewer that what kind of parking design the interviewer wants. For example, one interviewer may want a parking lot to be of 5 floors, whereas another interviewer is fine with a single floor parking lot.
In this section, we will use the object-oriented paradigm of Java to design the parking lot. Before going through this section, readers are required to have a good understanding of the object-oriented principles of Java.

The blocker represents the synchronization object responsible for this thread parking.
Thus we can note which object is responsible for the thread being parked, which can help for debugging and monitoring purposes.
The unsafe methods are called to set the parkBlocker value to the Thread instance.
Plant life is greatly reduced in this area. Most of the species that grow in this area are pioneer species. There are also some wooden plants such as cemara (Casuarina junghuhniana), mentinggi gunung (Vaccinium varingifolium), kemlandingan gunung (Albizia lophantha), acacia bark (Acacia decurrens) and bottom plants such as Javanese edelweiss or senduro (Anaphalis longifongila and Anaphalis javanica), Imperata cylindrica, Pteris sp., Themeda sp. and Centella asiatica.[10]
