Oracle asks for more time to finish Java 9

Eight weeks needed to sort out missing pieces of Jigsaw platform module system


Oracle's asked for more time to sort out Java 9 in light of the community's rejection of the proposed Java Platform Module System.

The chief architect of Big Red's Java Platform Group, Mark Reinhold, has hit the openjdk mailing list to address the vote against JPMS (JSR 376 , aka “Jigsaw”) due to land with JDK 9.

In his post, Reinhold says “This vote does not mean that JSR 376 is dead, nor that Jigsaw has been rejected. It only means that the Executive Committee raised a number of concerns that it wanted the JSR 376 Expert Group (EG) to address.”

And address them it shall, within the rules that allow expert groups 30 days to offer a revised spec to put to a second Executive Committee vote. That revision is due on or before June 26th, which is four days after the expected publication of JDK 9's first release candidate.

With that timeline now messed up, Reinhold reckons the safe thing to do is move the date of general release from July 27th, 2017 to September 21st, 2017.

By El Reg's count that's the fourth significant delay to JDK 9, which was first proposed to ship on September 22nd, 2016, then suggested for March 23rd, 2017. But in September 2016, Reinhold said the release had so many bugs it would be best to aim for June 22nd.

Plenty of those problems were Jigsaw-related. But Reinhold writes that Jigsaw's problems code and conceptual problems both look to be almost behind it, as the dissenters who voted it down appear to be satisfied with some new code and “additional clarifications” about its workings.

The Java community has until June 6th to make alternative suggestions, otherwise Reihnold's proposal will stick. At the time of writing his thread had received no public feedback, suggesting September 21st will be the day. Unless something else goes pear-shaped. ®

    As a slowdown in PC sales brings down prices for graphics cards, AMD is hoping to win over the market's remaining buyers with a bold, new claim that its latest Radeon cards provide better performance for the dollar than Nvidia's most recent GeForce cards.

    In an image tweeted Monday by AMD's top gaming executive, the chip designer claims its lineup of Radeon RX 6000 cards provide better performance per dollar than competing ones from Nvidia, with all but two of the ten cards listed offering advantages in the double-digit percentages. AMD also claims to provide better performance for the power required by each card in all but two of the cards.

    A futuristic design won't make people want to come back – just ask Apple

    After nearly a decade of planning and five years of construction, Google is cutting the ribbon on its Bay View campus, the first that Google itself designed.

    The Bay View campus in Mountain View – slated to open this week – consists of two office buildings (one of which, Charleston East, is still under construction), 20 acres of open space, a 1,000-person event center and 240 short-term accommodations for Google employees. The search giant said the buildings at Bay View total 1.1 million square feet. For reference, that's less than half the size of Apple's spaceship. 

    The roofs on the two main buildings, which look like pavilions roofed in sails, were designed that way for a purpose: They're a network of 90,000 scale-like solar panels nicknamed "dragonscales" for their layout and shimmer. By scaling the tiles, Google said the design minimises damage from wind, rain and snow, and the sloped pavilion-like roof improves solar capture by adding additional curves in the roof.

  • Pentester pops open Tesla Model 3 using low-cost Bluetooth module
    Anything that uses proximity-based BLE is vulnerable, claim researchers

    Tesla Model 3 and Y owners, beware: the passive entry feature on your vehicle could potentially be hoodwinked by a relay attack, leading to the theft of the flash motor.

    Discovered and demonstrated by researchers at NCC Group, the technique involves relaying the Bluetooth Low Energy (BLE) signals from a smartphone that has been paired with a Tesla back to the vehicle. Far from simply unlocking the door, this hack lets a miscreant start the car and drive away, too.

    Essentially, what happens is this: the paired smartphone should be physically close by the Tesla to unlock it. NCC's technique involves one gadget near the paired phone, and another gadget near the car. The phone-side gadget relays signals from the phone to the car-side gadget, which forwards them to the vehicle to unlock and start it. This shouldn't normally happen because the phone and car are so far apart. The car has a defense mechanism – based on measuring transmission latency to detect that a paired device is too far away – that ideally prevents relayed signals from working, though this can be defeated by simply cutting the latency of the relay process.
