Question
I have a simple WAR and want to server a static html file. I get a NumberFormatException because the DateHeader field contains a formatted Date instead of an expected String with milliseconds ... Can anyone help me out?

@janitza-bjag I don't understand.

The HTTP Date header must be a date, as specified: https://www.rfc-editor.org/rfc/rfc9110#field.date.

Is it you trying to get the Date field as a long, or it is Jetty that produces the error and you are not doing anything explicitly?

Do you have reproducer steps so we can reproduce the issue?

[janitza-bjag]

@sbordet Sorry, its about the HttpHeader.LAST_MODIFIED.
I do not set it explicitly, so I think its handled by Jetty.

I debugged into "org.eclipse.jetty.ee8.nested.Response" where the static method putHeaders is called. Here the NumberFormatExceoption occurs ...

[janbartel]

@janitza-bjag I think I've recently fixed this problem, see: #10463

@janbartel
In #10463 I only see commits for ee9 package, are they used in ee8 too?

[sbordet]

@janitza-bjag ee8 is mechanically copied from ee9 just changing the package names, so ee8 will have the fix.

[sbordet]

Closing as duplicate of #10463.
