[infinispan-issues] [JBoss JIRA] (ISPN-12307) Improve media type parsing

Improve media type parsing -------------------------- Key: ISPN-12307 URL: https://issues.redhat.com/browse/ISPN-12307 Project: Infinispan Issue Type: Enhancement Reporter: Dan Berindei Priority: Major Media type parsing has some problems with double-quoted parameters: * {{;}} and {{,}} are interpreted as parameter/media type separator even when they occur in a quoted parameter value * {{'}} is interpreted as a quoting character, the spec says only {{"}} must be used for quoting * Only spaces are allowed, not {{\t}}. * Spaces are allowed in too many places, e.g. {{type / subtype}} or {{parameter = value}} * Start and end quotes are removed from quoted parameter values, but the escaped characters inside are not unescaped. * Quotes are not added back in {{toString()}}, which makes deserialization fail if one of the parameters included an escaped double-quote (e.g. {{type/subtype; param="\""}}). Performance can also be improved, as we create many {{String}} instances via {{trim()}}, {{substring()}}, or {{split()}}. The clearest explanation of the media type grammar seems to be in https://tools.ietf.org/html/rfc7231#section-3.1.1.1 https://tools.ietf.org/html/rfc7230#section-3.2.6
