When I install the basic RPM package and run it, I get only this line: "libjvm.so<no newline>" as output, though when I run just the image bundle, it runs ok.
The binary files <image>/App1 and /opt/App1/App1 differs, while App1.cfg are the same.

Log:

No base JDK. Package will use system JRE.

Advice to fix: Please install required packages.
