(OFBIZ-10895)

Partially revert r1858094, just replaces "rmaps == null" by "rmaps.isEmpty()"

As Mathieu mentioned in dev:
<<Checking for ‘null’ here is not a solution since ‘resolveURI’ contract
it to return a non-nullable collection.
This commit is only bypassing the error handling.>>

As I said in r1858094:
<<This has been somehow broken by OFBIZ-10438 but actually it was already broken 
before but not for the same reason.>>

We need now to review/check how it worked in R15 where it's OK, and possibly 
implements the same
