Btw. in some other places we happily print the user name/id in the exception (but indeed this is test code so it should be no issue).
https://github.com/openjdk/jdk/blame/master/src/java.base/unix/classes/sun/nio/fs/UnixUserPrincipals.java#L144

leads to (test injdk21u-dev), the user name seems no we messed up because of the bad LDAP we had on the test system, that's why only the id shows up in the exception
