re: Tomcat 9 Java version required

Hi ,

I downloaded and configured Tomcat 9  - what version of Java does this version require?

I have installed:
java version "1.7.0_95"
OpenJDK Runtime Environment (rhel-2.6.4.0.el6_7-x86_64 u95-b00)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)



With:



JRE_HOME=/usr/mware/jdk1.7.0_17/jre



My OS is:  Red Hat Enterprise Linux Server release 6.5 (Santiago) 64bit

On startup.sh  now getting:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/catalina/startup/Bootstrap : Unsupported major.minor version 52.0
        at java.lang.ClassLoader.defineClass1(Native Method)
