RMI disabled, Java still listens on port 1099

When I execute netstat -tupan, one of the entries is the following:

tcp        0      0 :::1099  :::*         LISTEN      8778/java

However, I have removed all settings concerning RMI and JMX from the options passed to Java when it starts. My questions are:

1. Is RMI actually still enabled? I can connect to the port using telnet.
2. If not, why does Java still listen on the port?

Edit: I blocked the port using netcat: nc -l 1099. This prompted an error on the application startup, and it turns out that I have an MBean in the application which was automatically picked up by Spring on startup and registered.
