Re: Batik dependencies on JDK-Internal APIs

Hi Luis,
I'm trying to get an idea about how much community testing is happening
on JDK Early Access (EA)
builds, and to encourage more of it to happen.
Would you like me to send you availability emails for the Early Access
builds for the various JDK 8
updates & JDK 9 ?
I would really like to list your project along with a contact and link
to your CI on the wiki [0], is that
something you would be interested in ?
Rgds,Rory
