Issue:
We deployed the RHEV probe. The installation went well but the probe does not want to start.

Even with loglevel at 5 the probe file stays empty. 

I tried to manually starts the .jar file by running it from the command line as follows:

/opt/nimsoft/jre/jre7/bin/java -Xms32m -Xmx512m -Duser.language=en -Duser.country=US -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5006 -jar /opt/nimsoft/probes/application/rhev/rhev.jar

and here's the response.


Listening for transport dt_socket at address: 5006 Exception in thread "main" java.lang.UnsupportedClassVersionError: com/ca/probe/main/ProbeMain : Unsupported major.minor version 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$100(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source) 
Environment:
UIM (any version)
java_jre 1.7
Cause:
The RHEV probe requires JRE8, and will not work if only JRE7 is installed.
Resolution:
1. Download the java_jre 1.8 package into your UIM Archive.
2. deploy that package to the server where you intend to run the RHEV probe.
3. deploy the RHEV probe and it will now start successfully.
