I use a http filter and ContextLocals to store contextual information extracted from http request headers. It working nice with blocking http handler but not with non blocking code like ExceptionMapper<NotFoundException>.

When i entering “response” filter, ContextLocals is empty.

@Provider
@Priority(1)
public final class EntryPointHttpFilter implements ContainerRequestFilter, ContainerResponseFilter {

    @Override
    public void filter(final ContainerRequestContext containerRequestContext) {

        // Extract data from request headers

        // Init exec context
        ExecutionContext.initialize(...); //internally use ContextLocals.put("KEY", ctx)
    }

    @Override
    public void filter(ContainerRequestContext containerRequestContext, ContainerResponseContext containerResponseContext) {

        ExecutionContext.destroy(); //internally use ContextLocals.remove("KEY") with exception if ContextLocals.get() == null
    }
}

Controller code is executed in thread executor-thread-X, but error handler in vert.x-eventloop-thread-X.

How i can propagate my context ?
