1888636 - DOES_INSTALLATION_EXIST: Main Class Missing - Error in SWPM/MaxDB

Symptom

In a SAP installation with MaxDB database, Software Provisioning Manager tool (SWPM) fails with following error:

sapinst_dev.log
ERROR      <timestamp>
Error during execution of command identifier 'DOES_INSTALLATION_EXIST' : Exception in thread "main" java.lang.NoClassDefFoundError: com/sap/sdb/core/main/cmd/SdbCmdMain
Caused by: java.lang.ClassNotFoundException: com.sap.sdb.core.main.cmd.SdbCmdMain
                at java.net.URLClassLoader$1.run(URLClassLoader.java:255)
                at java.security.AccessController.doPrivileged(Native Method)

                at java.lang.ClassLoader.loadClass(ClassLoader.java:313)
Could not find the main class: com.sap.sdb.core.main.cmd.SdbCmdMain.  Program will exit.

There is a similar error message 'DOES_INSTALLATION_EXIST' explained in SAP Note #2207314, but the installation scenario is different and so is the solution.
#2207314 - DOES_INSTALLATION_EXIST: MaxDB Software must be installed before this class can be instantiated
