Solution: 

To fix the "java.lang.RuntimeException: Jar definition /user_projects/domains/oam_domain/config/fmwconfig/mapstore-coherence.jar provided is invalid. " error seen when starting the admin server, edit the oam-config.xml file and do the following changes:

a) Increment the version, search Name="Version"

e.g

 <Setting Name="Version" Type="xsd:integer">18</Setting>

to

<Setting Name="Version" Type="xsd:integer">19</Setting>

 b)Search for the JMXConfig component, that is the line "<Setting Name="JMXConfig" Type="htf:map">".

Below the "<Setting Name="FileSet1" Type="htf:map"> line replace the line
 "<Setting Name="LibraryOffset" Type="xsd:string">${COMMON_COMPONENTS_HOME}/modules/oracle.coherence</Setting>"
by
"<Setting Name="LibraryOffset"
Type="xsd:string">${common.components.home}/modules/oracle.coherence</Setting>"

and below <Setting Name="FileSet2" Type="htf:map"> replace the line
 "<Setting Name="LibraryOffset" Type="xsd:string"></Setting>"
 by
"<Setting Name="LibraryOffset" Type="xsd:string">${OAM_ORACLE_HOME}/server/lib/jmx</Setting>"
