What is really odd is that both com.google.common.collect.AbstractMapBasedMultimap and the suppossedly abstract com.google.common.collect.AbstractMultimap should come from the same bundle, so be compatible with each other. Unfortunately, Bug 496800 prevents us from knowing which Guava version is used. Whoever encounters this problem should thus please attach the output of About Eclipse > Installation Details > Configuration to this bug, so that we can reproduce it. Thank you in advance.
