> The mergeIndexes method in CoreAdminRequest class accepts an array of srcCores, but it
only merge the last core of array into targetCore. Related code as follows,
> if (srcCores != null) {
> 	for (String srcCore : srcCores) {
> 		params.set(CoreAdminParams.SRC_CORE, srcCore);
> 	}
> }
> The for-each loop above overrides the SRC_CORE value in params and only the last one
reserved when loop ends.
> We should remove the for-each loop and set SRC_CORE value with an array of srcCores.
> The code above is in CoreAdminRequest class line 330
