IIS Server not returning expected format for multipart Content-Type

[lauzond]

/zsync-core/src/main/java/com/salesforce/zsync/internal/util/HttpClient.java#L425
MediaType.parse() doesn't expect the format of the Content-Type header to be as provided by an older IIS Server version and results in error "Could not parse 'multipart/byteranges"

To workaround this issue:

Remove final from:
/zsync-core/src/main/java/com/salesforce/zsync/internal/util/HttpClient.java#L421

And insert the follwing code line before:
/zsync-core/src/main/java/com/salesforce/zsync/internal/util/HttpClient.java#L425

contentType = contentType.replaceFirst("multipart/byteranges; boundary=(<[^>]*?>)", "multipart/byteranges; boundary=\"$1\"");
