mina 2.0.2 - NullPointerException in AbstractPollingIoProcessor

[Guy Itzhaki]

Dear forum,

I'm using mina 2.0.2 and once in a while I get this error in the
console:

Exception in thread "pool-4-thread-1" java.lang.NullPointerException

      at
org.apache.mina.core.polling.AbstractPollingIoProcessor$Processor.run(Ab
stractPollingIoProcessor.java:1151)

      at
org.apache.mina.util.NamePreservingRunnable.run(NamePreservingRunnable.j
ava:64)

Source)

      at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown
Source)

      at java.lang.Thread.run(Unknown Source)

 

 

In my server I have use a NioSocketAcceptor and at some point, although
it might not be relevant, I unbind() the acceptor, replace IoFilter with
a new one and then bind() it again.  

 

BTW, I didn't find line 1151 in AbstractPollingIoProcessor...

Any idea why this might happen?

Thanks in advance,

Guy
