Thursday, April 7, 2011

open standards organization, and the reputation of Java
itself as an open technology...”

Thursday, April 7, 2011

29. What’s the Point?

meaningful.”
• Oracle did nothing about licenses before EC had to vote
• “...it finally made it clear to me that my vote was worthless.”
• “...Oracle’s expressed intent to proceed with SE7/8 whatever the
outcome of the vote...” = rubber stamp
-Tim Peierls
Thursday, April 7, 2011

30. But Java Will Be Fine
• “...it actually is not all that crucial for Java to move
forward”
• “The big boys want big apparent forward motion
because it means more stuff to sell, more contracts
and control”

ASF Resigns from JCP Executive Committee
Thursday, April 7, 2011

32. We Are Sooo Over
• Java SE7/8 vote was last chance for JCP EC to step
up
• “...by accepting Oracle's TCK license terms for
Java SE 7, they let the integrity of the JCP's
licensing structure be broken”
• “JCP is not an open specification process”
• ASF removing all representatives from JSRs
Thursday, April 7, 2011

33. Oracle’s Response?

forward...”
