Solution:- This issue occurs when the property 'abpm.connect.cache.enable' is set to yes in server-configure.properties file.  

This is an obsolete property and isn't needed. Once this property is disabled or set to no then this issue will be resolved and you shall be able to start Adeptia Services.
