my program was blocked, I used the jstack command for analysis, the next thread took the lock "0x0000000603f02ae0", and other threads could not get the lock.
I have been waiting for at least one hour, but the thread has not been unlocked, my question is why thread_state is RUNNING and stops at java.util.HashMap.getEntry (HashMap.javahaps47)? is it an oracle (sun) JDK bug?
my jdk version:
java version "1.6.0_21"
Java (TM) SE Runtime Environment (build 1.6.0_21-b06)
Java HotSpot (TM) 64-bit server VM (build 17.0-b16, mixed mode)
