From a comment I received in private, I must re-state something that I said about being a JCP/JSPA rule.
Disclosure: not a lawyer, not an IP specialist, not a OSS guy. I (think I have) learned this from seating on the JCP meetings.
I said "and only Oracle can lead a platform JSR (like Java EE - that's a JCP/JSPA rule).". It's more of combination of the JSPA and the JCP Process document. Only Oracle can (that's my understanding) fulfill the use of the trademarks and they must approve the ballot for it to go thru, so there wouldn't be a JSR for a Platform without Oracle's blessing. Maybe "lead" was the wrong term.
From the JSPA:
8. Use of Trademarks. Subject to any other rights and obligations You may have pursuant to other agreements with Oracle with respect to the use of trademarks owned or otherwise licensable by Oracle, You may refer to Oracle’s Java technology or programming language to the same extent as the general public, provided that such reference is not misleading or likely to cause confusion. The Third Party Usage Guidelines for Oracle Trademarks are currently available on the web at
http://www.oracle.com/html/3party.html.
And the JCP Process Doc:
Umbrella Java Specification Request (UJSR): A JSR that defines or revises a Platform Edition or Profile Specification. A UJSR proceeds through the JCP like any other JSR.
3.7.7 JSR ballot rules
Ballots to approve Umbrella JSRs that define the initial version of a new Platform Edition Specification or JSRs that propose changes to the Java language are approved if (a) at least a two-thirds majority of the votes cast are "yes" votes, (b) a minimum of 5 "yes" votes are cast, and (c) Oracle casts one of the "yes" votes. Ballots are otherwise rejected.
