Java 8 not yet supported

Postby skoehler » Wed Mar 19, 2014 7:02 pm

Java 8 is not yet supported by leJOS. But we're working on it.

For the time being, please download Java SE embedded version 7 from here:
http://www.oracle.com/technetwork/java/ ... index.html

Download the file called ejre-7u51-fcs-b13-linux-arm-sflt-headless-18_dec_2013.tar.gz (ARMv5 Linux - Headless EABI, SoftFP ABI, Little Endian).
It's the last ARM build in the list.

Hi skoehler,

I've just flash my NXT and got HelloWord on it.

I did't noticed this topic before installing java on my w7. I downloaded the last release from java "jdk1.8.0_05"

I compiled and downloaded it to the nxt ( lejos 0.9) with sucess.

Should I unistall it and install jdk1.7 as ou mentioned?

This thread is about the EV3, not the NXT. Using Java 8 with leJOS NXJ is OK.

Is there a discussion on what work is needed to get java 8 to work on the ev3?

I'm very experienced in java, but new to lejos.

If there's some specific issues that need attention, I might be able to help out.

The next release will support Java 8 (already there in git master). But the JRE side of things is rather complex. We are talking with Oracle to make it easier for leJOS users. What Java 8 features are you looking for?

Lambdas are the main java 8 feature I'm interested in.

I was going to start poking around and see if I could get some of the sensor stuff to have a streaming api or poke around with some of the APIs and see where some of the interfaces could be refactored to make sense as functional interfaces (so they could be implemented in lambdas).

If nashorn was on there, I was going to poke around with the javascript a bit too.
