The infamous "someone" should update the WSDG to call out Java (64 bit) as a prerequisite for the docs.

"First time around building my dev environment (win10 x64), the Java installer picked 32-bit packages.

Similar messages to what you are seeing. Fixed by reinstalling 64-bit Java."

Does the Java warning sound important? Is there something I should do to try to increase the java heap size?  This machine should have loads (c20GB)  of memory available..

Odd, Java isn't called out as an installable by the Developers Guide but obviously ascidoctorj requires it.  Looking at my VM I have an old version of Oracle Java 8 installed and absolutely no idea where it came from:

> java -version
java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)

> (Get-Command java.exe).Source
C:\Program Files (x86)\Common Files\Oracle\Java\javapath\java.exe

The invocation of asciidoctorj (if installed via chocolatey it will be <ChocoInstallDir>\lib\asciidoctorj\tools\asciidoctorj-x.x.x\bin\asciidoctorj.bat) sets JVM options for memory.

I've never come across this before, and can't remember it being reported elsewhere.

Best regards,

Martin
