I have tried to build a Windows 32-bit JDK-11. While I was successful in building a 64-bit Windows JDK, the attempt for 32-bit failed:
Here's what I did: $ bash configure --with-boot-jdk=/cygdrive/c/jdk-10.0.2 --disable-warnings-as-errors --with-target-bits=32 ... ==================================================== The existing configuration has been successfully updated in /cygdrive/c/jdk/jdk11/build/windows-x86-normal-server-release using configure arguments '--with-boot-jdk=/cygdrive/c/jdk-10.0.2 --disable-warnings-as-errors --with-target-bits=32'.

ERROR: Build failed for target 'all' in configuration 'windows-x86-normal-server-release' (exit code 2) On a meta-level: Is a JDK for Windows 32-bit just built no longer or is it completely abandoned as a platform?
