> We currently check if a resource is present by making sure that the file exists locally. There can be a case where the LocalizationTracker thinks that it has the resource if the file exists but with size 0 or less than the "expected" size of the LocalResource. This JIRA tracks the change to harden the isResourcePresent call to address that case.
