emscripten doesn't find/use locally installed Java

This is similar to emscripten-core/emsdk#1142 but for Java.

I have a system installed Java 8 newer than what emcripten bundles.

Unfortunately there are no working instructions for doing so.

I tried using the command "emsdk uninstall java-8.152-64bit", then edited .emscripten to point to the locally installed java jre 1.8.0.192

But now CI builds fail with the error message "error: error: tool is not installed and therefore cannot be activated: 'java-8.152-64bit'"
which indicates that something deep inside emscripten is checking for the specific bundled java install status.

Installing the bundled java again causes emscripten to use it instead of the version/path specified in .emscripten

Please provide instructions for doing this right, and don't make such hidden boobytraps for sysadmins trying to run a minimal install.

OS version: Windows 10.0.22000.778
emscripten version: 3.1.14 (4343cbec72b7db283ea3bda1adc6cb1811ae9a73)

Command invoked by CI build script: %EMSDK_PATH%\emsdk.bat activate 3.1.14
Output from command:
Resolving SDK version '3.1.14' to 'sdk-releases-upstream-ade9d780ff17c88d81aa13860361743e3c1e1396-64bit'
error: error: tool is not installed and therefore cannot be activated: 'java-8.152-64bit'

Supplemental issue:
"emsdk install java_8.152-64bit" sets all unpacked files to the timestamp of running the unpack, not the upstream timestamps or the timestamps in the downloaded zip file.
