Re: ARM6 + Java SE Embedded 8u6

So, if I understood well, it is not possible to have Java 8 SE Embedded on Raspberry Pi? Is there any way in which I could create a compact profile from the JDK 8 for ARM that will work on the Raspi? I have tried all embedded java 8 versions in my Raspberry with no luck, and it a bit dissapointing....

Re: ARM6 + Java SE Embedded 8u6

Hi, Java SE Embedded is a commercial product optimized for low memory footprint. You can use it on the Raspberry Pi, but most hobbyists would just use the Oracle JDK for ARMv6/7: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-arm-downloads-2187472.html Regards, Henrik -- Oracle Java team

Hi all, We (Oracle) have a lot of customers and partners who are interested in accessing low-level I/O like GPIO, I2C, UART and similar interfaces from Java ME and SE.

Re: SIGSEGV

Check with the phidgets and/or libusb projects if they can help you troubleshoot. This is a crash in interrupt processing in native code (libusb_interrupt_transfer as per your thread dump). They need to figure out why that is happening. Make sure you save the core dump if you want them to help you. ...

Re: SIGSEGV

The most likely scenario is a bug in libusb. Since it's a native library, it can cause the JVM process to crash.

Re: Running javafx using WebView webEngine on RPi fails

Why Oracle has stripped down the Java8 to a creepy "lite" version? That's a mystery to me, too. For the first time it breaks the deployment of J2SE JARs. We're not talking about the "profiles" coming with Java8, but the "normal" J2SE. Imagine my surprise when I some JavaFX tests which run on the st...

Re: Oracle license fees for Java on Raspberry Pi are cheap

To clarify the clarification: The quoted 60 cents per RPi unit is for a perpetual license. You can also choose to sign up to a support contract which is around 20% of that (approx 12 cents per unit per year) and gives access to unlimited updates (Java 8, Java 9, Java 4711...) and 24/7 support.
