Cause
Application Performance Management (APM) installer to upgrade to SP3 require Java 1.8. The issue occurs because the installer is not finding Java 1.8 but another version.
Environment
APM 10.7 GA CentOS 7
Resolution
1. Check what is the Java version used by the system with the command line > java -version
2. If more than one Java version is installed on the server, you may select the one in <EM_HOME> with next command line
> sudo alternatives --config java
From the list select the number that corresponds to the Java installed under <EM_HOME> This will change the default Java used by the System.
3. Once you make sure "java -version" return the correct JRE, re run the installer.
