    Expression cache.clear() is a void method call, and thus it cannot be parameterized
    Expression LOG.warning("The thread waiting for the Save Attachment Temporary command was interrupted.") 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
