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

Question

I get the following exception when I try to deploy my webApp to 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 at weblogic.application.internal.ExtensibleModuleWrapper.start(ExtensibleModuleWrapper.java:140) at weblogic.application.internal.flow.ModuleListenerInvoker.start(ModuleListenerInvoker.java:124) at weblogic.application.internal.flow.ModuleStateDriver$3.next(ModuleStateDriver.java:213) at weblogic.application.internal.flow.ModuleStateDriver$3.next(ModuleStateDriver.java:208) at weblogic.application.utils.StateMachineDriver.nextState(StateMachineDriver.java:42) Truncated. see log file for complete stacktrace Caused By: 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 at org.jboss.weld.logging.WeldMessageConveyor.<init>(WeldMessageConveyor.java:61) at org.jboss.weld.logging.WeldMessageConveyerFactory.getDefaultMessageConveyer(WeldMessageConveyerFactory.java:27) at org.jboss.weld.logging.LoggerFactory.<init>(LoggerFactory.java:37) at org.jboss.weld.logging.LoggerFactory.loggerFactory(LoggerFactory.java:51) at org.jboss.weld.bootstrap.WeldBootstrap.<clinit>(WeldBootstrap.java:126) Truncated. see log file for complete stacktrace 

Does anyone have an idea why? My application uses Errai

Based on @JoseM's comment, this link helped. The quick fix that I applied to now is to downgrade my guava library from 16.0.1 to 14.0.1 .
