I think that File("") has different semantics in Java 25. Rather than being
`false` it is the primary working directory. Here's an example. Which means
this test is probably failing on main? Is there a scheduled run of tests on
main or similar I could check? Or I could open a new PR with no changes.
```
echo 'System.out.println("Java " + System.getProperty("java.version") + ":
new File(\"\").exists() = " + new java.io.File("").exists());' | docker run
--rm -i eclipse-temurin:21-jdk jshell -s -
echo 'System.out.println("Java " + System.getProperty("java.version") + ":
new File(\"\").exists() = " + new java.io.File("").exists());' | docker run
--rm -i eclipse-temurin:25-jdk jshell -s -
```
gives:
```
~ ❯ echo 'System.out.println("Java " + System.getProperty("java.version") +
": new File(\"\").exists() = " + new java.io.File("").exists());' | docker run
--rm -i eclipse-temurin:21-jdk jshell -s -
