Description

When configuring the regions of a provider using the context properties, if there are no specific endpoints for each region, the following exception is thrown:

Multiple entries with same value: <regionId1>=<endpoint> and <regionId2>=<endpoint>
java.lang.IllegalArgumentException
	at com.google.common.collect.ImmutableMap.checkNoConflict(ImmutableMap.java:150)
	at com.google.common.collect.RegularImmutableBiMap.<init>(RegularImmutableBiMap.java:131)
	at com.google.common.collect.ImmutableBiMap.copyOf(ImmutableBiMap.java:210)
	at org.jclouds.suppliers.SupplyKeyMatchingValueOrNull.get(SupplyKeyMatchingValueOrNull.java:53)

This is caused by the use of a Guava BiMap in the SupplyKeyMatchingValueOrNull, which enforces unique keys and values.

The implementation should be changed to allow regions being configured in the context properties.
