Hello,
from the system requirements:
- Oracle Java SE 7 64-bit (update 10 or newer)
In case it is intended to run SAP GUI for Java also as stand alone application, the installation of the JDK is required. For Oracle's support statement please refer to http://www.oracle.com/technetwork/java/javase/config-417990.html
from the release notes of 7.30 rev 5:
- Launching the application bundle now is possible without having Java 6 installed. Before, the Finder used to check for the availability of the Java 6 runtime, which at the end, has not been used anyway. As a result of the chances, it is also technically no longer possible at all to run SAP GUI for Java 7.30 using Java 6.
For information on installed JDKs, run /usr/libexec/java_home -V in a terminal window.
It looks like you have been running SAP GUI for Java prior to 7.30 rev 5 on Java 6, not Java 7, due to missing Java 7 JDK.
Best regards
Rolf-Martin
