jextract/jpackcore not packaged in Java 8 JDK for Windows

[JamesKingdon]

A customer reported not being able to find jextract in their Semeru Java 8 installation on Windows, so I downloaded the latest build of the jdk (ibm-semeru-open-jdk_x86-32_windows_8u432b06_openj9-0.48.0.zip) and confirmed that I couldn't find it either.

This might be intentional, since you don't need to run jpackcore on Windows. I find it in the jre/bin directory for other platforms.

[pshipton]

The doc indicates AIX, Linux, macOS.

We are excluding Windows on jdk8.
https://github.com/ibmruntimes/openj9-openjdk-jdk8/blob/openj9/jdk/make/CompileLaunchers.gmk#L524

I see in jdk11+ jextract/jpackcore are included.

[pshipton]

We could include it, but it does bundle all the dlls on Windows, which afaik aren't needed since the data is included in the core file.
Any particular reason the customer was looking for it on Windows?

It's not present on Linux either (I checked 0.46.0).

[pshipton]

I see it in xlinux 0.46. It's in jre/bin and not bin.

[keithc-ca]

You're right (I didn't look there). Shouldn't it be in both places (in a JDK)?

It wouldn't hurt but nobody is complaining about that afaik.

I think because we are used to asking for system cores to be processed with jextract by default. I noticed that the docs for jextract don't mention Windows. I don't know for sure if we get everything we need without using jextract or not - it would be amusing if we've been asking for it for years without needing it.

For the record, those tools were explicitly omitted via ibmruntimes/openj9-openjdk-jdk8#205.
