Re: OpenJDK-jre and sun.arch.abi
Some one installed this VM: https://raspberrypi.stackexchange.com/questions/45976/how-do-i-update-j ava-8-in-raspbian/68114#68114 No idea what vm this is, but it has the system property "sun.arch.abi" with "gnueabihf" set. Here Im able to figure out the multiarch tupel is "arm-linux- gnueabihf". On debian the abi is missing, so I only can binary parse /proc/self/exe to figure out on what system im running - I did it and it has its drawbacks too. Now I decided to brute force try to load the candidates "arm-linux- gnueabihf" and "arm-linux-gnueabi" and hope that one succedes. But I would prefer to have the system property sun.arch.abi properly set. Arne

OpenJDK 9 or newer support armhf or newer only *if* you're using the Hotspot VM, if you're using the Zero VM (Zero being the one running on any architecture), then the older ARM ABIs are supported.

Re: OpenJDK-jre and sun.arch.abi
My problem is, I wrote a lib that replaces gnu.io (http://github.com/aploese/spsw/) for serial port access - so I must detect the real abi on all platforms, not just debian. Or is gnueabi outdated and thus needs no support at all?

OpenJDK-jre and sun.arch.abi
Hi, Im trying to figure out under java what platform Im on. there are some System properties, but on the debian arm platform "sun.arch.abi" is missing. This would give me the distiction between gnueabi and gnueabihf - wether I have hard or soft floating point. On the raspberry PI3 its defined... So I think its a bug, but where to file a bug or fix it? Thanks, Arne
