ReentrantLock$Sync.tryRelease java.lang.IllegalMonitorStateException

早上一来，例行性的看主要环境的运行情况，发现有个环境中有如下异常：

直接找到对应的源码看了下逻辑，同时网上搜了下，又仔细看了下代码和javadoc，报错的代码如下：

        try {
            if (lock.tryLock() || lock.tryLock(1, TimeUnit.MICROSECONDS)) {
                // 此处为业务逻辑...
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        } finally {
            lock.unlock();
        }

javadoc中关于lock.unlock的说明如下：

没有注意到释放未持有的锁会导致该异常，更改为如下，问题即可解决。

        try {
            if (lock.tryLock() || lock.tryLock(1, TimeUnit.MICROSECONDS)) {
                // 此处为业务逻辑...
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        } finally {
            if (lock.isHeldByCurrentThread()) { lock.unlock(); } }
