[cdi-dev] cdi-dev Digest, Vol 57, Issue 33

Sun Aug 30 10:29:44 EDT 2015

Looking at the requirements for SE Embedded (on the lower side of SE)
probably helps:
http://www.oracle.com/technetwork/java/embedded/embedded-se/documentation/javase-embedded-sysreq-2043454.html

The 3 MB binary app size Romain mentioned is a good example. Could be a bit
steep for Embedded, but as an upper end it sounds reasonable.

Btw. although Rod Johnson and Bob Lee were listed as co Spec Leads, pretty
much every initial contribution and effort came from Google/Bob:
https://jcp.org/en/jsr/detail?id=330

The EG had a couple of others like Tapestry, but I am not sure, when it
e.g. adopted JSR 330 instead of its own DI library if it ever fully
supported it to date?
