我遇到一个java.lang.illegalmonitorstateexception,它只在第一个execlinkedop调用中发生一次。我想我遗漏了一些jason过程,应该很好地同步这些函数。execlinkedop可能正在其末尾重新生成一些上下文,以便为下一次调用修复此条件。
下面的论坛说,这种问题可能发生在缺少同步(foo)调用的情况下。http://www.jguru.com/faq/view.jsp?eid=128732

正如alessadro ricci所建议的,您得到的每个java.lang.illegalmonitorstateexception都应该取决于您试图从不属于cartago的线程调用cartago/工件代码的事实。
假设您有自己的线程t(cartago外部)想要访问一个工件a调用某个公共方法(例如,其目的是更新工件的obs状态……),那么,从您刚才调用的线程代码:
其中art是对artifact java对象的直接引用。
