from time to time, I receive this kind of warning when fuse 3.3.08 running without any particular activities

WARN  - ActiveMQConnection             - Async exception with no exception listener: java.io.EOFException

java.io.EOFException

        at java.io.DataInputStream.readInt(DataInputStream.java:358)

This is normal ?
