### Description of PR
The S3A isolated classloader test appears to be broken with newer JDKs'
restrictions on reflection access. The test fails with
`java.lang.IllegalAccessException: Attempt to lookup caller-sensitive method
using restricted lookup object`
### How was this patch tested?
```
./mvnw -pl :hadoop-aws -am -Dtest=none
-Dit.test=ITestS3AFileSystemIsolatedClassloader.java clean verify
```
with Java 17 and 21.

- [x] Object storage: have the integration tests been executed and the
endpoint declared according to the connector-specific documentation?
- [na] If adding new dependencies to the code, are these dependencies
