I have a Windows 7 x32 machine that has Oracle JRE 1.7 installed. I want to use the Commons Daemon to launch a different process, minifi (different from the one that needs Java 7) as a service, but I want minifi to use the jvm.dll provided by OpenJDK 8.
So, I have specified the OpenJDK 8 jvm.dll in the java tab, and set the mode in startup and shutdown to jvm.

org.apache.nifi.minifi.StdErr java.lang.UnsupportedClassVersionError: org/apache/nifi/minifi/MiNiFi : Unsupported major.minor version 52.0 minifi is getting launched with the installed Java 7. It looks like the jvm startup is still referencing the registry somewhere to find java? Unfortunately, I cannot uninstall Java 7 or change the default java in the registry to OpenJDK 8. Am I just out of luck, and thus need to switch to exe instead of jvm?
