JavacPlugin.loadJavacParserClass() checks if the classloader contains ManJavacParser, and if not, adds it. When building with SBT, this method is invoked multiple times, sometimes concurrently, which can result in an "attempted duplicate class definition" error: java.lang.LinkageError: loader ...
Java之多线程(1) - Race Condition引起的性能问题 Race Condition(也叫做资源竞争),是多线程编程中比较头疼的问题。特别是Java多线程模型当中,经常会因为多个线程同时访问相同的共享数据,而造成数据的不一致性。为了解决这个问题,通常来说需要加上同步标志“synchronized”,来保证数据的串行访问。但是“synchronized”是个...
EVALUATION The reason of the hang is race condition in JavawsSysRun. It is possible that secureThread used to run "actions" finishes it work and sends notifyAll() BEFORE application thread reaches wait(). In such case application thread may wait forever. Proposed solution is attached. Note t...
It may seem that the termsrace conditionanddata racehave the same meaning, while — in fact — they are different. In the book,Java Concurrency in Practice, it says: "Not all race conditions are data races, and not all data races are race conditions, but they both can cause concurrent ...
竞争条件是当多个线程同时执行同时访问共享资源时在多线程编程中发生的问题。正确使用同步可以避免出现竞态...
Everything in this post is pretty obvious, but I’ve observed real confusion about the distinction between data race and race condition by people who should know better (for example because they are doing research on concurrency correctness). Muddying the waters further, even when people are per...
race condition: 正确性依赖于事件发生的相对时间。 check-and-act是race condition中的一种,指的是基于check的结果进行操作。由于check和act并非是原子的,进行act时check的结果可能已经无效,那么基于check所进行的act就可能带来问题。 见如下的lazy单例类: ...
The software safety requires the data consistency in the software. In the multithreaded object-oriented programming, the coherency problem, also called a race condition, may destroy the data consistency. In order to overcome the coherency problem Java sets up the "synchronized" mechanism. How...
