    Expression LOG.severe(e.getLocalizedMessage()) cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression cache.clear() is a void method call, and thus it cannot be parameterized

    Type org.columba.core.io.StreamCache of variable cache does not match with type java.util.logging.Logger of variable LOG
    • Make classes org.columba.core.io.StreamCache and java.util.logging.Logger extend a common superclass
