80-80: Consider reintroducing specific error handling forIOExceptionin theacceptmethod.The analysis of the codebase shows that while some usage of the
acceptmethod is wrapped in try-catch blocks, the handling is either too broad (catchingThrowable) or lacks specific handling forIOException. This could result in unhandled exceptions in certain scenarios, potentially affecting application robustness.
- ConcurrentExportTests.java: Uses try-catch but catches
Throwable, which is too broad.- ConcurrentStreamResourceWriter.java: Uses try-finally but lacks specific
IOExceptionhandling.Reintroducing specific error handling for
IOExceptionin theacceptmethod would enhance error management and maintain application resilience.Analysis chain
Consider reintroducing error handling for
IOException.The removal of the try-catch block for
IOExceptionin theacceptmethod may lead to unhandled exceptions propagating up the call stack. This could affect the robustness of the application, as exceptions during the workbook writing process will not be logged or handled locally. Consider reintroducing error handling to maintain resilience and provide meaningful error messages.Scripts executed

IOException Handling is Adequately Managed
The removal of the
IOExceptioncatch block inPdfStreamResourceWriterdoes not adversely affect the application. The exception is handled inConcurrentStreamResourceWriterthrough atry-catchblock, ensuring thatIOExceptionis managed appropriately. Additionally, the usage inGridExporterconfirms the integration ofPdfStreamResourceWriter, though specific exception handling is not detailed. Overall, the current structure maintains application stability.Scripts executed

No immediate impact from removing the IOException catch block in CsvStreamResourceWriter.accept
The
acceptmethod inCsvStreamResourceWriterdoes not appear to be invoked anywhere in the current codebase. Therefore, removing theIOExceptioncatch block does not have an immediate impact on the application. However, if this method is intended to be used in the future, ensure that any calls to it handle theIOExceptionappropriately.Scripts executed

LGTM!The
buildRowmethod is well-structured and correctly uses streams and lambda expressions to construct a CSV row. It ensures necessary conditions are met before proceeding.
Line range hint
28-60:
Consider the impact of propagatingIOException.By removing the
catchblock forIOException, any exceptions during the CSV writing process will now propagate to the caller. While this can improve upstream error handling, it also removes local logging, which may reduce visibility into specific failures during export operations. Ensure that upstream code is equipped to handle these exceptions appropriately and consider adding logging at a higher level if needed.
Sonar requests "Define and throw a dedicated exception instead of using a generic one" in
LGTM since the exception would be swallowed by the framework, and there is no place for error handling. |
