WLS 12.2.1 QUICK installer ignores response file

I was trying to install fmw_12.2.1.0.0_wls_quick.jar using the usual command line:
/usr/java/jdk1.8.0_65/bin/java -jar /opt/install/fmw_12.2.1.0.0_wls_quick.jar -silent -logLevel finest -debug -responseFile /opt/install/installfmw1221.rsp -invPtrLoc /etc/oraInst.loc
in vain... it would keep saying "Oracle Home not found, using default /tmp/hsperfdata_wls122/wls1221 " even if there is a variable ORACLE_HOME=/opt/oracle/fmw1221 in my response file.

Then I run "/usr/java/jdk1.8.0_65/bin/java -jar /opt/install/fmw_12.2.1.0.0_wls_quick.jar –help" and I my attention is drawn on this statement:

-responseFile   
        Location of the response file containing input for OUI. Ignored by quick installers.

So... the right syntax for QUICK installer is:

/usr/java/jdk1.8.0_65/bin/java -jar /opt/install/fmw_12.2.1.0.0_wls_quick.jar -silent -logLevel finest -debug ORACLE_HOME=/opt/oracle/fmw1221 -invPtrLoc /etc/oraInst.loc
