java.lang.IllegalAccessError: tried to access method com.google.common.collect.MapMaker.makeComputingMap(); from WeldMessageConveyor

Question

I get the following exception when I try deploying my webApp on weblogic12:

weblogic.application.ModuleException: java.lang.IllegalAccessError: tried to access method com.google.common.collect.MapMaker.makeComputingMap(Lcom/google/common/base/Function;)Ljava/util/concurrent/ConcurrentMap; from class org.jboss.weld.logging.WeldMessageConveyor

Any one has an idea why? My application uses Errai

Solution

Based on @JoseM comment, this link helped. A quick fix I applied for now was to downgrade my guava lib from 16.0.1 to 14.0.1.
