> I have 2 DB tables with multiple associations between them
> Table A (id, name, tableb_id)
> Table B (id, name tablea_id)
> First, an association gets correctly created for tableA with the name TableA_TableB. While creating an association for TableB, the code searches for an association named "TableA_TableB" instead of searching/creating "TableB_TableA" association. The faulty code is at 
> org.apache.olingo.odata2.jpa.processor.core.access.model.JPAEdmNameBuilder.build()
>    if (end1Name.equals(end2Name)) {
>       associationName = end1Name + UNDERSCORE + end2Name;
>       associationName =
>           associationName + UNDERSCORE + multiplicityToString(association.getEnd1().getMultiplicity()) + UNDERSCORE
>               + multiplicityToString(association.getEnd2().getMultiplicity()) + Integer.toString(count);
>     } else {
>     if (end1Name.compareToIgnoreCase(end2Name) > 0) {
>         associationName = end2Name + UNDERSCORE + end1Name;
>       } else {
>         associationName = end1Name + UNDERSCORE + end2Name;
>       }
>     	associationName = end1Name + UNDERSCORE + end2Name;
>       if (count >= 1) {
>         associationName = associationName + Integer.toString(count - 1);
>       }
> The fix is to create associationName = end1Name+UNDERSCORE+end2Name
> instead of arranging the names in ascending order.
