Basic provider route throws exception

Opening http://localhost:9000/authenticate/basic (thus the examples HTTP basic auth) causes the following error on samples/java/play-authenticate-usage@3f70e03:

[error] application -

I've tried debugging and I didn't figure where's the problem, maybe as I'm new to the framework too. I'm going to test previous versions and will report any findings. I appreciate any help.

Due to dependency resolving problems, I can't put my finger on the exact commit that's introducing the error.
cd16266 is the last commit that I found has no problem with basic authentication. ef6b81a is the earliest commit that I could confirm for affected basic authentication.
I didn't check 8418466, cc8b1d9, b873200 due to failing dependency downloads, neither did i check 98036b9 due to a failing build with sbt run.

When I authenticated successfully in an unaffected version, affected versions redirected from http://localhost:9000/authenticate/basic without prompting an error. Of course, resetting the browser session got back the error prompt.

hmm, the diff from cd16266 to ef6b81a is not terrible and it shouldn't be the form changes.

[joscha]

Ah, I think I found it - its the Optionals handling.

I pushed a fix in 02138d9, can you please give that a try @adpes?

Unfortunately, I do still experience the issue.

How can I make sure that contents of folders respectively code or samples/java/play-authenticate-usage/modules/ are used in the example? I reckon mismatching byte-code and source-code when debugging.
What's the difference in commenting the line

  // Comment the next line for local development of the Play Authentication core:
  // Use the latest release version when copying this code, e.g. "0.9.0"
  "com.feth" %% "play-authenticate" % "0.9.0-SNAPSHOT"

and uncommenting the line

  //  Uncomment the next line for local development of the Play Authenticate core:
  //lazy val playAuthenticate = project.in(file("modules/play-authenticate")).enablePlugins(PlayJava)

for sbt's dependencies? There are pgp and routing errors thrown with the commented and uncommentented line, respectively.

Ah yes, there are a few places in the various files of the sample where it says `Comment here` - you need to find all of them for it to use the local code. Alternatively, can you check if the commit with the fix produced a snapshot build? It should have, then you can just replace the release version with he snapshot version and it should work as well. Cheers, Joscha
