> Our team uses Ivy/IvyDE, and noticed Eclipse hanging today/yesterday, to the point of
being unusable.
> I tracked it down to Eclipse asking IvyDE "is this your file?", which  IvyDE's IvySettingsContentDescriber
used XMLHelper.parse to answer, but then Xerces hung while trying to load the XML file's DTD.
> So, the problem was the DTD being unavailable, but it seems like XMLHelper should turn
this off, especially if the schema parameter is null, and it's in non-validating mode.
> The attached patch turns off external DTD fetching when XMLHelper is already in non-validating
mode.
> This avoids the wire call, which speeds up the XMLHelper.parse by at least 100%, ~250-300ms
when fetching the DTD, to ~100-150ms when not. (And this is the happy case, in the worst case,
waiting for the timeout if the DTD is unavailable, takes ~20s).
