OpenJDK: need little help with ObjC

[Sergio Had]

Could someone help with one chunk of ObjC code in OpenJDK?

I have finally built the thing and it works, from looks of things, but I get a message on startup:
36-25% /opt/local/var/macports/build/_opt_PPCSnowLeopardPorts_java_openjdk8/openjdk8/work/jdk8u-jdk8u372-ga/build/openjdk8/images/j2sdk-image/bin/java -version

openjdk version "1.8.0_372"
OpenJDK Runtime Environment (build 1.8.0_372-root_2024_07_09_15_56-b00)
OpenJDK Zero VM (build 25.372-b00, interpreted mode)

This seems to be related to the code, which upstream has switched to block syntax (it does not build with GCC), so I had to use its earlier version.
>From commit message it seems upstream also had this startup issue:
https://github.com/openjdk/jdk8u/commit/c29d997ca180ba5d812df7745c668cfc906be20b

Can we fix it properly without blocks?
