JDK for Linux on ARM
This release includes support for a new platform, JDK for Linux on ARM. The product offers headful support for ARMv6 and ARMv7.
[color=#FF0000]No support is available for WebStart, Plug-In, Java Flight Recorder, and Garbage First (G1) Collector.[/color] Also some features of the Serviceability Agent are not available for Linux on ARM platform.
So, I’m guessing that lack of WebStart support may be an issue?
