Issue description

The Kurento Group Call Example crashes when a second party joins a room where already another participant is waiting

Context

I was just trying to run the sample :)

I launched the the Java app like so:

mvn -U clean spring-boot:run  -Dspring-boot.run.jvmArguments="-Dkms.url=ws://webrtc:8888/kurento"

My KMS runs at webrtc:8888 in my local network.

When the first party ("Alice") joins, the own video appears top left 320x240. Then on a second party ("Bob") joins the same room and boom.

The log from the Java side:

~/Documents/tmp/kurento-tutorial-java/kurento-group-call $ mvn -U clean spring-boot:run     -Dspring-boot.run.jvmArguments="-Dkms.url=ws://webrtc:8888/kurento"
