two java.util tests failed with "IOException: There is not enough space on the disk"

The following tests failed in the JDK17 CI:

java/util/zip/ZipFile/Zip64SizeTest.java
java/util/jar/JarFile/LargeManifestOOMTest.java

Here's a snippet from the Zip64SizeTest.java log file:

Here's a snippet from the test task's stdout:

[2021-01-16T03:20:04,272Z][DEBUG][pool-3-thread-1][c.o.j.s.e.u.DiskProfiler] Several file stores with the same name:
[2021-01-16T03:20:04,288Z][INFO][pool-3-thread-1][c.o.j.s.e.u.DiskProfiler] Available disk space before execution (T:): 6.9 GiB / 46.0 GiB (14.9%)

The second line says there is 6.9GB available before the test
setup started. I would think that's enough space for a test run,
but I don't know these tests.

This line from c.o.j.s.e.u.DiskProfiler is also interesting:

    Several file stores with the same name:

and why is there nothing showing the names of the file stores?
Could be nothing or could be the root cause? I don't know.

Minimally, I think the tests should be updated with additional
info about the file store's currently available space.

Normally Tier1 failures would start as P2, but these two failures
are very strange so I'm starting this at P3 so it can be evaluated
by Core-Libs triage. After evaluation, I have no problem if it gets
lowered to P4.
