Class MDCThreadPoolExecutor

java.lang.Object

java.util.concurrent.AbstractExecutorService

java.util.concurrent.ThreadPoolExecutor

org.pepsoft.util.mdc.MDCThreadPoolExecutor

All Implemented Interfaces:

Executor, ExecutorService

public class MDCThreadPoolExecutor
extends ThreadPoolExecutor

A variant of ThreadPoolExecutor which adds two behaviours:

• The MDC diagnostic context map of the thread that executes the execute(Runnable) method is propagated to the runnable task.
• If the runnable task throws an exception, it is wrapped in an MDCCapturingRuntimeException to preserve a copy of the MDC diagnostic context at the moment the exception occurred.
