StaticFileHandler with cache throws java.nio.file.NoSuchFileException

[witoldsz]

Hi,
I am using StaticFileHandler in my application (to serve static content), like this:

vertx.createHttpServer().websocketHandler(socket -> {
[...]
})
.requestHandler(new StaticFileHandler(vertx, "...path..."))
.listen(config.getHttpPort());

When webapp requests a document which does not exist, the StaticFileHandler throws an exception and browser waits forever:

SEVERE: Exception in Java verticle
java.lang.IllegalStateException: Failed to check file: java.nio.file.NoSuchFileException: ...path...
    at org.vertx.mods.web.StaticFileHandler.handle(StaticFileHandler.java:184)
    at org.vertx.mods.web.StaticFileHandler.handle(StaticFileHandler.java:37)
    at org.vertx.java.core.http.impl.ServerConnection.handleRequest(ServerConnection.java:180)
[...]

The problem does not exist when caching is disabled. My workaround is this:

.requestHandler(new StaticFileHandler(vertx, "...path...") {
            @Override
            public void handle(HttpServerRequest req) {
                try {super.handle(req);} catch (Exception e) {
                    req.response().setStatusCode(404).setStatusMessage("").end();
                }
            }
        }).listen(config.getHttpPort());

It does look like a bug to me, doesn't it?
