Hi, everybody:
I met a problem when updating an arraylist. I put a Pojo object "Lobby" in a
replicated TreeCache. The "Lobby" object has an Arraylist which contains
objects "Player". The TreeCache is replicated on two nodes. At each node, a
couple of transactions update the ArrayList. When two transactions on two nodes
are updating the Arraylist at the same time, a write conflict will happen and
then both abort. Then, each transaction wil retry later. At the time of retry ,
I met exceptions on each node. On one node , the exception is
[java] java.lang.RuntimeException: java.lang.IllegalStateException:
AOPInstance.incrementRefCount(): source fqn: /lobby/0/players/17 is already
present.
On another node, the exception is:
[java] java.lang.RuntimeException: java.lang.RuntimeException:
InternalDelegate.incrementRefCount(): null aopInstance.
Then, I cannot continue the execution. I tried to change to use HashMap to
replace ArrayList, but the the same problem still exist.
Anybody here kowns what is the reason?
Thank you very much.
