Andrzej Bialecki updated TIKA-863:
-----------------------------------
Description: MailContentHandler is called from RFC822Parser, and it creates
AutoDetectParser on each call to parse(...). The process of creating
AutoDetectParser involves reading TikaConfig (not cached), which in turn
involves parsing XML config files. Apart from the fact that this process is
wasteful and heavy, in addition in a highly concurrent setup it leads to
multiple threads blocking on SAX parser creation. (was: MailContentHandler is
