Java open source development kit based on AzulSystems' Zulu / Open JDK.
I am @NathanTippy from ociweb.com and we are building a light weight pure Java solution for the Grove Edison and Grove RaspberryPI platforms. We are using the Zulu JDK and Open JDK to avoid licensing costs. Analog, Digital and I2C work has already been prototyped and demonstrated.
Would you consider sponsoring some or all of this work? We have one engineer (w/ 20yrs Java experience) working on this part time now and a number of interested and skilled engineers who could begin work on this quickly.
This entire project is open source and BSD licensed to encourage wide adoption and usage. Due to the popularity of Java this would make a great addition to your product.
