As far as I know there are no plans from oracle to ship java for 32 Bit - but maybe I misunderstand the situation. If I'm correct - what do we all do if we need to support 32-Bit libraries (dlls)? And whats about 32 Bit OSes out there? Currently this seems to be a huge impact in the future but as I said - maybe I'm wrong. Fact is that we can't download a Java 10 runtime in 32 Bit as there are only 64 Bit Download-Links.
Had a similar issue, just with Java 11. Eventually, I found a 32bit JDK and JRE for Java 11 on https://adoptopenjdk.net/ (for the Hotspot JVM). With the 32bit JDK, I successfully connected to a 32bit dll. I hope this is useful for others who face a similar situation.
