Remove throw statements from finally blocks in benchmark tests

[sonarqube-agent]

This PR was automatically created by the Remediation Agent's Scheduled backlog remediation feature.

Why these issues? These fixes address critical control-flow bugs where throw statements in finally blocks suppress exception propagation, creating silent failures and hindering debugging. The issues are highly automatable with clear, localized remediation across 5 files (BenchmarkTest00012, BenchmarkTest01491, BenchmarkTest01743, BenchmarkTest02037, and BenchmarkTest02208), representing a high-impact improvement to exception handling correctness.

Fixed 5 critical SonarQube issues (java:S1143 and java:S1163) by removing throw statements from finally blocks across multiple benchmark test files. Throwing exceptions in finally blocks suppresses the original exception that was thrown in the try or catch block, making error diagnosis difficult; these changes preserve proper exception propagation by replacing throws with comments or logging calls.

Fixed Issues

java:S1163 - Refactor this code to not throw exceptions in finally blocks. • CRITICAL • View issue

Location: src/main/java/org/owasp/benchmark/testcode/BenchmarkTest00012.java:102

Why is this an issue?

If an exception is already being thrown within the try block or caught in a catch block, throwing another exception in the finally block will override the original exception. This means that the original exception’s message and stack trace will be lost, potentially making it challenging to diagnose and troubleshoot the root cause of the problem.

What changed

This hunk replaces a throw new ServletException(e) statement inside a finally block's catch clause (catching javax.naming.NamingException) with a comment indicating the exception is intentionally suppressed. The original code threw an exception from within a finally block, which could mask any exception already being thrown from the try block. By removing the throw statement, the code no longer throws exceptions in finally blocks, preserving the original exception and preventing it from being overridden by the exception thrown during cleanup.

java:S1143 - Remove this throw statement from this finally block. • CRITICAL • View issue

Location: src/main/java/org/owasp/benchmark/testcode/BenchmarkTest01491.java:95

Why is this an issue?

Using return, break, throw, and so on from a finally block suppresses the propagation of any unhandled Throwable which was thrown in the try or catch block.

What changed

Directly fixes the bug where a throw statement ('throw new ServletException(e)') inside a finally block would suppress propagation of any unhandled Throwable thrown in the try or catch block. The throw is replaced with a LOGGER.log() call that logs the exception at WARNING level instead, so control flow no longer jumps out of the finally block. This removes the 'throw new ServletException' at line 95 of BenchmarkTest01491.java, resolving the static analysis warning about using throw statements in finally blocks.

This hunk removes the 'throw new ServletException(e)' statement from a finally block at line 95 of BenchmarkTest01743.java and replaces it with a comment. Throwing an exception in a finally block masks any original exception that was thrown in the corresponding try or catch block, making it difficult to diagnose the root cause. By removing the throw statement, the original exception is no longer overridden and can propagate properly. This addresses the code smell about not throwing exceptions in finally blocks, as the refactored code no longer risks masking the original exception.

What changed

This hunk removes a throw statement from within a finally block. Throwing an exception from a finally block suppresses the propagation of any unhandled exception that was thrown in the corresponding try or catch block. By replacing the throw new ServletException(e) with a comment (effectively swallowing the exception), the original exception from the try/catch block is no longer suppressed. This fixes the bug where a jump statement (throw) forces control flow to leave the finally block, which would prevent proper exception propagation.

This hunk removes a 'throw' statement from within a 'finally' block in BenchmarkTest02208.java at line 106.
