postinstall fails if there is a space in user name

FULL PRODUCT VERSION :
java version "1.8.0_144"
Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Darwin 16.7.0 Darwin Kernel Version 16.7.0: Thu Jun 15 17:36:27 PDT 2017; root:xnu-3789.70.16~2/RELEASE_X86_64 x86_64

EXTRA RELEVANT SYSTEM CONFIGURATION :
User name has a space in it.

A DESCRIPTION OF THE PROBLEM :
This line in the ./postinstall is incorrect and will fail if the username has a space in it:

${SU} - ${CONSOLE_USER} -c "${LSREGISTER} -f ${JWS_APP}"

I believe the correction should be:

${SU} - "${CONSOLE_USER}" -c "${LSREGISTER} -f ${JWS_APP}"


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create an OSX user with a space in name e.g. "my user" and attempt JDK installation

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
JDK install succeeds.
ACTUAL -
JDK install fails
