Fixed Issues (42 total)

1. 5 Lambda Expressions (S1612) - Replaced lambda expressions with method references in test files

   • XapiClientTests.java: Changed () -> response.block() to response::block and () -> iterator.next() to iterator::next

2. 24 Unthrown Exception Declarations (S1130) - Removed unnecessary throws clauses

   • Removed unused throws IOException from 14 test methods in StatementTests.java
   • Removed unused throws IOException from 3 test methods in GroupTests.java, ContextActivitiesTests.java, and AttachmentTests.java
   • Removed unused throws InterruptedException from 9 test methods in XapiClientTests.java

3. 4 Deprecated JWT API Usages (S1874) - Updated to JJWT 0.12.x non-deprecated API

   • Statement.java: Changed from deprecated setClaims() and signWith(key, algorithm) to claims() and signWith(key, Jwts.SIG.RS512)

4. 4 Duplicate Test Implementations (S4144) - Fixed tests to actually test intended functionality

   • DeleteActivityProfileRequestTests.java: Removed duplicate test methods
   • XapiClientTests.java: Fixed VoidedStatement tests to call getVoidedStatement() instead of incorrectly calling getStatement()

5. 2 Empty Code Blocks (S108) - Added explanatory comments

   • XapiClientAutoConfigurationAuthorizationTest.java and XapiClientAutoConfigurationUsernamePasswordTest.java: Added comments to empty catch blocks

6. 1 Unused Import - Removed unused import statement
