Install failure installing Liberty Tools after having installed Liberty Developer Tools

Installing this sequence:

1. Enterprise Java - 2024-06
2. LDT - https://marketplace.eclipse.org/content/ibm-liberty-developer-tools
3. LT 24.0.9 driver (internal-only but this is now the 'main' contents at the time of this issue).
   the third step fails to complete.

So far this has only been observed on Windows.

An error is shown in the install wizard UI that maps to this message in the workspace log:

!MESSAGE Missing requirement: Liberty Tools Support for Language Servers 24.0.9.202409170137 (io.openliberty.tools.eclipse.lsp4e 24.0.9.202409170137) requires 'osgi.bundle; org.eclipse.lsp4mp.jdt.core 0.0.0' but it could not be found

There are some earlier messages in the logs like these:

!ENTRY org.eclipse.equinox.p2.metadata.repository 4 0 2024-09-20 11:29:53.178

!MESSAGE Unexpected error loading extension: org.eclipse.equinox.p2.metadata.repository.compositeRepository

Reproduce the Windows installation sequence for Enterprise Java 2024-06, Liberty Developer Tools, and the Liberty Tools 24.0.9 driver, then inspect the workspace log and the missing org.eclipse.lsp4mp.jdt.core requirement. Trace the Equinox p2 and ECF HttpClient5 errors shown in the stack trace; done means Liberty Tools installs successfully after Liberty Developer Tools.
