Description

Running control.sh from ignite-2.7.6 release candidate on MacOS with empty JAVA_HOME produces no output - the script terminates without any action.

The reason is the following line in bin/control.sh:

javaMajorVersion "${JAVA_HOME}/bin/java"

Since JAVA_HOME is empty, the argument passed to the function is invalid and the function terminates the script. I suggest replacing the ${JAVA_HOME}/bin/java with just $JAVA because it is already determined earlier in the scope. The suggested fix works in my environment for all options of JAVA_HOME
