--------------------------------------------------------------
Does the GetMeta response start with the standard xml header (which IIRC has an
encoding)? Is that not being set? Would setting that make everything work?
e.g.
{code:java}
<?xml version="1.0" encoding="UTF-8"?>{code}
I'm guessing that if that is set, the parser will do the right thing
automatically?

> XML parser fails with SAXParseException when trying to deserialize service

> UIMA-AS client running on windows
> Service runs on linux
> The client sends getMeta request and receives a response from a service. The
> client tries to deserialize the meta and gets:

> A workaround for the above was to set: -D"file.encoding-UTF-8" on the client.
> Review the code and provided a fix. Perhaps XML InputSource has a way to set
> encoding. The default should be UTF-8. Seems like we need a new uima-as a new
> property (or command line arg) to override the default in case a user needs
> different encoding.
