Removing Oracle JDK and re-configuring update-alternatives

Please check the scenario below:

sudo update-alternatives --config java
There are 5 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status 0 /usr/lib/jvm/java-7-openjdk-i386/jre/bin/java 1071 auto mode 1 /opt/java/jdk1.8.0_25/bin/java 1 manual mode * 2 /usr/lib/jvm/java-1.8.25-i386/bin/java 1 manual mode 3 /usr/lib/jvm/java-1.8.25-i386/bin/javac 1 manual mode 4 /usr/lib/jvm/java-1.8.25-i386/bin/javaws 1 manual mode 5 /usr/lib/jvm/java-7-openjdk-i386/jre/bin/java 1071 manual mode
echo $JAVA_HOME
/opt/java/jdk1.8.0_25/bin/java

OK, It's really messed up!! I need to clean and remove absolutely everything from the start !

I tried

sudo update-alternatives --remove "java" "/opt/java/jdk1.8.0_25-i386/bin/java"

but the table shown above remained unaltered !!

Please help me out !!!!

Could you please try to run with arguments without quotes? It works in my case:

svyatoslav@svyatoslav-DNS:~$ sudo update-alternatives --config java
