This paper presents a technique for deadlock detection of Java programs. The technique uses typing rules for extracting infinite-state abstract models of the dependencies among the components of the Java intermediate language – the Java bytecode. Models are subsequently analysed by means of an ...
Towards Detecting Thread Deadlock in Java Programs with JVM Introspection Deadlock is a common error for multithread Java programs. Existing Java thread deadlock detection solutions either require source code, or are built on non... W Yan,J Zhao,M Huang,... - IEEE Computer Society 被引量:...
To this end, we propose a method for static detection of deadlock in Java libraries. Our goal is to determine whether client code exists that may deadlock a library, and, if so, to enable the library writer to discover the calling patterns that can lead to deadlock. Our flow-sensitive,...
Traditional deadlock detection algorithms depend on finding cycles in lock graphs created from the application code. Usually, these approaches suffer from ... Zhida Luo,R Das,Q Yao - IEEE Fourth International Conference on Software Testing 被引量: 40发表: 2011年 Multithreaded Test Synthesis for ...
I'm curious if there's an appetite for adding JMX based deadlock detection. I think deadlocks are good candidates to emit as events because: They are not timed, so do not make sense as spans Its useful for debugging to include high cardi...
As a deadlock detection error is a safe-to-retry error and the user is expected to handle these in all application code, since there may be legitimate deadlocks at any time, this behavior is actually by design to gain scalability. The following describes a scenario where a deadlock...

Perhaps the crudest form of deadlock detection and recovery is the watchdog timer. In event of a deadlock, the timer will elapse (deadlock detection),and reboot the system (recovery). As a last ditch safety net for very infrequent or as yet undiscovered deadlocks this is acceptable. ...

Deadlock detection on the other hand is allowing the system to enter a deadlocked state. After entering, the system uses the information that it has to break deadlock. As an example, consider multiple processes accessing files. The operating system is able to keep track of all of the files...
