**weblogic空闲进程，weblogic.work.ExecuteThread.waitForRequest表示在等待请求。备用线程,这些线程不需要处理当前请求被放入standby池内，当活动的线程池内需要更多线程时，这些线程将被激活。**  
"\[STANDBY\] ExecuteThread: '31' for queue: 'weblogic.kernel.Default (self-tuning)'" daemon prio=10 tid=0x00007ff1d802d000 nid=0xf38e in Object.wait() \[0x00007ff154bca000\]

**socketReader线程提高了weblogic处理客户端请求的速度和能力，12c默认会启动4个，进程是0,1,2,3。**

**waiting on condition,这种等待通常是线程主动等待或正在进行IO操作，而并非等待其他线程释放资源，这里在代码里调用了sleep方法。还有wait(),join()方法也可以导致这种状态。**
