Hello Andre,

As far as I'm aware, support for 32 bit on Macosx has not been supported by anyone for a very long time. I would assume it far from trivial to get it to work.
In fact, I wonder if there *ever* have been 32-bit macOS support in OpenJDK. I believe we only inherited a 64-bit port from Apple.

Dear members,

For compatibility reasons with older 32bit i386 architecture dylibs via
JNI, I'm trying to build a 32bit version of jdk12u on Mac OS X.

I'm using the following configure command:
"bash configure
--with-boot-jdk=/Library/Java/JavaVirtualMachines/openjdk12/Contents/Home
--with-target-bits=32"

But I'm getting the following build errors when I try to build
macosx-x86-client-release and macosx-x86-server-release:
"ERROR: Build failed for target 'default (exploded-image)' in configuration
'macosx-x86-client-release' (exit code 2)
