-----------------------------------
Summary: Add JDK 17 compile options for maven-surefire-plugin in
hadoop-tos module
Key: HADOOP-19726
URL: https://issues.apache.org/jira/browse/HADOOP-19726
Project: Hadoop Common
Issue Type: Improvement
Components: hadoop-tos
Affects Versions: 3.5.0
Reporter: Shilun Fan
Assignee: Shilun Fan
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}

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.
