Update Java version from 1.8 to 11 in pom.xml

Summary

Updated the java.version property in pom.xml from 1.8 to 11 as the first step in migrating the banking application from Java 8 to Java 11. This change updates the Maven compiler target and source compatibility settings.

Changes:

• Line 18 in pom.xml: <java.version>1.8</java.version> → <java.version>11</java.version>

Verification Completed:

• ✅ Maven compilation (mvn compile) passed successfully with Java 11

Review & Testing Checklist for Human

This is a straightforward property change, but Java version upgrades can have runtime implications that aren't caught at compile time. Please verify:

• Run full test suite (mvn test) to ensure all unit and integration tests pass with Java 11
• Test the application end-to-end locally:
  • Start the application with mvn spring-boot:run
  • Verify API endpoints work correctly via Swagger UI at http://localhost:8989/bank-api/swagger-ui.html
  • Test basic operations (customer creation, account operations, transfers)
• Confirm deployment environment has Java 11 installed and configured

Notes

• Spring Boot 2.1.4.RELEASE supports Java 11, so no framework upgrades are needed for this change
• This is part 1 of the Java 8 → 11 migration process
• Future steps may require updating dependencies or addressing deprecated API usage
