2845067 - FATAL: Main class "com.sap.inst.jdbc.connect.JdbcCon" cannot be started

After upgrade from 7.0x to a later NetWeaver Java, such as 7.5, starting/stopping the Java server with startsap/stopsap may give error in the command line:

FATAL: Main class "com.sap.inst.jdbc.connect.JdbcCon" cannot be started:
FATAL: java.lang.UnsupportedClassVersionError: com/sap/security/core/server/secstorefs/InvalidStateException : Unsupported major.minor version 52.0

FATAL: com.sap.engine.offline.OfflineToolStart will abort now with exitcode 2

this issue doesn't appear to actually effect the starting and stopping of the server, but the error is received nonetheless.
