Uninstall legacy Java versions in CPACS

SC Number 04498998

Problem Description:

JRE v6 and v7 were identified as critical vulerabilities in all CPACS servers running Linux.
Site: CPACS 6.0 SP6
Additional Findings:
- Found v7 is used by SYBASE
# env | grep JAVA
SCC_JAVA_HOME=/opt/sybase/15.7/shared/JRE-7_0_21_64BIT

- Also confirmed that an older version v6 is still present
# ls -altr /opt/sybase/15.7/shared/ | grep JRE
drwxrwxr-x. 8 sybase sybase 4096 Aug 15 2014 JRE-6_0_24_32BIT
drwxrwxr-x. 8 sybase sybase 4096 Aug 15 2014 JRE-6_0_24_64BIT
drwxrwxr-x. 6 sybase sybase 4096 Aug 15 2014 JRE-7_0_21_64BIT
drwxrwxr-x. 6 sybase sybase 4096 Aug 15 2014 JRE-7_0_21_32BIT

- Found that JDK version is v8
# java -version
java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) Server VM (build 25.161-b12, mixed mode)

Question:
Since Java v8 is already installed in the server site is requesting to uninstall v6 and v7 and use v8.
