Peter Levart provided the attached reproducer (ProxyRace.java) for the race condition. It is configured to run for 5 seconds and when run on a desktop machine it is very consistent in manifesting the error on th
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...
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...
When you confirm that you have a race condition in which shut down timing prevents a system dump, you can try to obtain a dump file in two ways: Try to prevent the system from shutting down before the dump file is taken. Add a delay near the end of the Java virtual machine (VM) ...
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 ...
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 ...

The Go language is generally safe, in that errors in your program do not lead to unpredictable crashes (unless you use the facilities in the unsafe package). There is one classic cause of problems, however, which Go does not protect you from: race conditions. A race condition occurs when ...
四,OSCache 在 Race Condition 下缓存重建的特殊场景 简单地说,就是: 线程1 正在重建缓存; 线程2 读取缓存时得到 NRE 异常,主动 cancel update; 线程1 重建缓存完毕,却发现状态被改为了 UPDATE_CANCELLED ,与期望不符,于是抛出异常 java.lang.IllegalStateException。
A race condition can be difficult to reproduce and debug because the end result is nondeterministic and depends on the relative timing between interfering threads. Problems of this nature can therefore disappear when running in debug mode, adding extra logging, or attaching a debugger...
