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...
Java中的 race-condition有什么用？在Java线程的那里使用呢？竞争条件是当多个线程同时执行同时访问共享...
UnsafeCachingFactorizer类的2个成员lastNumber和lastFactors的set()和get()方法是原子的,但是该类不是线程安全的。因为从整体上看,2次写入和2次读取都不是同时进行的,UnsafeCachingFactorizer类仍然存在race condition. java的synchronized机制使用的锁是可重入锁,即同一个线程可以多次申请持有同一把锁而不会引起死锁。

That is - a race condition between two (or more) threads might accidentally(偶然) drop an entry causing an extra cache miss - no biggie(无足轻重). Or, it may cause one thread to re-cache an entry that didn't need it. Also no biggie. In other words, a slightly imprecise(略微不准...
race condition竞用条件: 并发线程在同一个内存地址上操作 其中至少一个是写操作 内存没有使用同步机制 注意:满足竞用条件时,不一定产生数据竞争。 Data race occurs when at least two threads access the same memory location , with at least one of them writing data to that location and these accesses ...
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 ...
