Openjdk11 cannot launch on armv6

[TheEdward162]

System

Either of these freshly unpacked armv6l targets:

• https://alpha.de.repo.voidlinux.org/live/current/void-rpi-musl-PLATFORMFS-20210218.tar.xz
• https://alpha.de.repo.voidlinux.org/live/current/void-rpi-PLATFORMFS-20210218.tar.xz

Package openjdk11-11.0.5+10_4

Expected behavior

java runs java VM and lets me do java things

Actual behavior

$ java
Error occurred during initialization of VM
Server VM is only supported on ARMv7+ VFP

Steps to reproduce the behavior

1. get armv6 void (both glibc and musl)
2. xbps-install openjdk11
3. java

As a side note: I am able to get Zulu OpenJDK11 build running on the glibc target

What ARM device do you have? We can try to get the build info from Zulu and use in our build, maybe.

I'm running it on Raspberry Pi Zero W Rev 1.1:

$ cat /proc/cpuinfo
processor	: 0
model name	: ARMv6-compatible processor rev 7 (v6l)
BogoMIPS	: 697.95
Features	: half thumb fastmult vfp edsp java tls
CPU implementer	: 0x41
CPU architecture: 7
CPU variant	: 0x0

Hardware	: BCM2835

Additionally I also tried AdoptOpenJDK arm32 build in the meantime but it just segfaults.

I can confirm there seems to be an incompatibility, at least in the configuration void ships:
