Tests with Native Image, classpath resources and the File api.
Everything is under FilesystemTests. Use Graal JDK, I've tested with Graal 23.
Run the tests on the JVM, they should all pass:
./gradlew test
Run the tests in native image, 3 tests will fail, that is on purpose:
./gradlew nativeTest
Find the details of what works and what doesn't in the test file.
This was created to support a Testcontainers native-image issue.
I tried a TC patch to TC work by using the Path API instead of File, but there's another issue
which is that TC uses org.apache.commons:commons-compress, and that also does file operations,
some of which are not supported. Specifically, TarArchiveEntry#readOsSpecificProperties, used in
the constructor, uses Files.getOwner which is just not supported in native image.
