NullPointerException in ProtocolCodecFilter.filterWrite -------------------------------------------------------
Key: DIRMINA-679 URL: https://issues.apache.org/jira/browse/DIRMINA-679 Project: MINA Issue Type: Bug Affects Versions: 2.0.0-M4 Reporter: John J. Franey Looks like filterWrite obtains a reference from the session's attributes, but the desired attribute is not there. I am running max of 250 datagram sockets under load test for my application. Connections last about 60 seconds and released. Almost immediately another connection is obtained. Over a period of two hours running this load test, this exception occured twice. org.apache.mina.filter.codec.ProtocolEncoderException: java.lang.NullPointerException at org.apache.mina.filter.codec.ProtocolCodecFilter.filterWrite(ProtocolCodecFilter.java:312) at org.apache.mina.core.filterchain.DefaultIoFilterChain.callPreviousFilterWrite(DefaultIoFilterChain.java:506) at org.apache.mina.core.filterchain.DefaultIoFilterChain.access$7(DefaultIoFilterChain.java:501) at org.apache.mina.core.filterchain.DefaultIoFilterChain$EntryImpl$1.filterWrite(DefaultIoFilterChain.java:814) at org.apache.mina.core.filterchain.DefaultIoFilterChain$TailFilter.filterWrite(DefaultIoFilterChain.java:740) at org.apache.mina.core.filterchain.DefaultIoFilterChain.callPreviousFilterWrite(DefaultIoFilterChain.java:506) at org.apache.mina.core.filterchain.DefaultIoFilterChain.fireFilterWrite(DefaultIoFilterChain.java:498) at org.apache.mina.core.session.AbstractIoSession.write(AbstractIoSession.java:418) at org.apache.mina.core.session.AbstractIoSession.write(AbstractIoSession.java:359) ....
