Concurrent executions of 'installLiberty' task result in "java.io.EOFException: Unexpected end of ZLIB input stream"

[scottkurz]

E.g. in the MP Starter GHA check: https://github.com/eclipse/microprofile-starter/actions/runs/5580681548?pr=486
we have serviceA and serviceB doing a gradlew libertyPackage in two threads, simultaneously.

This task depends on 'installLiberty'.

One of the invocations completes successfully... the other fails with:

To honour the JVM settings for this build a single-use Daemon process will be forked. See https://docs.gradle.org/6.9.4/userguide/gradle_daemon.html#sec:disabling_the_daemon.
Daemon will be stopped at the end of the build 
> Task :installLiberty FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':installLiberty'.
> java.io.EOFException: Unexpected end of ZLIB input stream

I tried a couple of setup tweaks, none of which made a difference:

1. Running with a common daemon vs. running each invocation in its own daemon instance (note the message I pasted above has each using its own instance, --no-daemon
2. varying Gradle version.... not sure I took 100% accurate notes but I believe I tried both 6.9.4 and 6.8.3
3. varying LGP version.. I believe I tried v3.3.1 and v3.5.2
