RFR: 8145388: URLConnection.guessContentTypeFromStream returns image/jpg for some JPEG images

[Ramanand Patil]

HI all,

 

Please review this small fix for Bug  - https://bugs.openjdk.java.net/browse/JDK-8145388

 

Bug Description - For some JPEG images the method java.net.URLConnection#guessContentTypeFromStream will return the MIME type image/jpg, which is not a valid, registered IANA mime type for JPEG images.

 

Webrev - http://cr.openjdk.java.net/~ntv/ramanand/8145388/webrev.00/

 

Fix - Since "image/jpg" is not a valid Content Type, the method should return "image/jpeg" when APPn marker segment has 'EE' as a marker type.

 

 

Regards,

Ramanand.
