Hi, 

I use jstack PID command on my program in java and I got this output. 

[code]
"MapOutputCopier attempt_201108092223_0002_r_000013_1_0.2" prio=10 tid=0x00007f565c0b4000 nid=0x5f92 in Object.wait() [0x0000000041840000]  
   java.lang.Thread.State: WAITING (on object monitor)  
        at java.lang.Object.wait(Native Method)  
        at java.lang.Object.wait(Object.java:485)  
        at org.apache.hadoop.mapred.ReduceTask$ReduceCopier$MapOutputCopier.run(ReduceTask.java:1276)  
        - locked <0x00007f5668a910c0> (a java.util.ArrayList)  
[/code]

At one line, I've got " - locked <0x00007f5668a910c0> (a java.util.ArrayList)". I'd like to know what this hexadecimal address points to, to know which arraylist is . Is this possible? 

Thanks,
