Even after fixing the initial cause of this issue (see commit 12992), another problem appears subsequently, while trying to connect to the scheduler :

There seems to be a workaround to this issue though :

The workaround consits of changing the Static classpath of the Matlab JVM by editing the classpath.txt file located in MATLAB/toolbox/local
The following 4 jar files, need to be added manually to the classpath :

/dist/lib/ProActive.jar
/dist/lib/ProActive_Scheduler-core.jar
/dist/lib/ProActive_ResourceManager.jar
/dist/lib/ProActive_SRM-common.jar

The commit 12994 allows this workaround
