> Currently, the {{hadoop-tos}} module does not have the JDK 17 compile options
> configured for the {{{}maven-surefire-plugin{}}}, which causes the following
> error during unit test execution:
> {code:java}
> java.lang.IllegalStateException: Failed to set environment variable at
> org.apache.hadoop.fs.tosfs.util.TestUtility.setSystemEnv(TestUtility.java:120)

> This error occurs due to the module system restrictions in JDK 17, where
> reflection cannot access private fields in the
> java.util.Collections$UnmodifiableMap class.
>
> To resolve this issue, JDK 17 compile options have been added to ensure the
> maven-surefire-plugin works correctly in a JDK 17 environment. This PR adds
> the necessary compile options for maven-surefire-plugin to support JDK 17,
> fixing the error and ensuring that unit tests can run smoothly.
