On startup, Sybase Control Center checks SCC_JAVA_HOME for Java version
definition. If SCC_JAVA_HOME is undefined, Sybase Control Center
checks for installed JREs in this order:
- SYBASE_JRE7_64
- SYBASE_JRE7
- SYBASE_JRE7_32
Sybase Control Center then sets SCC_JAVA_HOME to the first
value it finds in this list.
