Alternating between x86 and arm java builds

Question

I have a need to alternate between and x86 zulu java build and the arm build. Is there a way to do this? I am running on an apple M1. I've set my terminal to open using rosetta I have the config set to true for sdkman. I've then installed the zulu 21 but I still see the arm version. Is this not possible anymore with sdkman? I've found this article but it doesn't seem to work for me. Any suggestions are appreciated.

 % cat ~/.sdkman/etc/config
sdkman_auto_answer=false
sdkman_auto_complete=true
sdkman_auto_env=false
sdkman_beta_channel=false
sdkman_checksum_enable=true
sdkman_colour_enable=true
sdkman_curl_connect_timeout=7
sdkman_curl_max_time=10
sdkman_debug_mode=false
sdkman_insecure_ssl=false
sdkman_rosetta2_compatible=true
sdkman_selfupdate_feature=true
% cat `which java` | file -
/dev/stdin: Mach-O 64-bit executable arm64
~ % java -version
openjdk version "21" 2023-09-19
OpenJDK Runtime Environment Zulu21.28+85-CA (build 21+35)
OpenJDK 64-Bit Server VM Zulu21.28+85-CA (build 21+35, mixed mode, sharing)

Answer 1

I haven't looked at the git history, but right now there is no reference to sdkman_rosetta2_compatible within the code, so it must have been dropped as it was temporary from what that article alludes to.

Interestingly enough, I did see the env SDKMAN_PLATFORM in there being used when downloading SDKs, which is actually being set in ~/.sdkman/var/platform and has a value of darwinarm64 (on m1). With that env I am able to list and install x86 SDKs on my m1 with the below:

SDKMAN_PLATFORM=darwin sdk list java
SDKMAN_PLATFORM=darwin sdk install java 11.0.9-zulu
sdk use java 11.0.9-zulu
cat `which java` | file -

Which will output the following

/dev/stdin: Mach-O 64-bit executable x86_64

If that doesn't work then try flushing the cache (sdk flush tmp) and then try again.
