Description

leveldb persistence fails to start due to errors as given below

Caused by: java.lang.NoSuchMethodError: com.google.common.base.Objects.firstNonNull(Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object;

The problem seems to be because of multiple jars having the same classes

guava-12.jar
pax-url-aether-1.5.2.jar

The class present in pax-url-aether-1.5.2.jar gets loaded causing level db to fail.
