Examples of FetchException

com.data2semantics.yasgui.shared.exceptions.FetchException
com.google.step2.http.FetchException
Thrown when something goes wrong while fetching data over HTTP
freenet.client.FetchException
Thrown when a high-level request (fetch) fails. Indicates why, whether it is worth retrying, and may give a new URI to try, the expected size of the file, its expected MIME type, and whether these are reliable. For most failure modes, except INTERNAL_ERROR there will be no stack trace, or it will be unhelpful or inaccurate.
