Exception when executing play-scala-secure-session-example

[antonini]

I received an exception while trying to execute the project.

....

Environment
SBT version: 1.3.2
JAVAC: 13 (Oracle)
JAVA: 13+13
play-samples branch: 2.7.x
libsodium: 1.0.18

[wsargent]

That's really odd. Is there a way you can reproduce this?

[antonini]

Well, here are the steps that I've done:
Installed JDK from Oracle.
brew install sbt (to upgrade it)
brew install libsodium
Cloned https://github.com/playframework/play-samples/
Accessed the folder play-scala-secure-session-example
sbt run.

Today I've tried forcing upgrade my brew, libsodium, sbt and the error persists.
Attached is the logs.log of the execution today.

Hi @antonini, can you try again with JDK1.8 or JDK11?

I've noticed this is actually a compilation error (not a runtime error):

[info] Fetched artifacts of

and I wonder if JDK13 introduced a breaking change.

[antonini]

@ignasi35 You are right!
Is a problem with JDK 13.
I downgraded to JDK 11. and it builds and run.

The problem is when trying to compile using the JDK 13.
I've tried some different scenarios as is explained bellow (with logs):

• Building and running with JDK 11 log-java11.txt - IT WORKS!
• Building and running with JDK 13 log-java13.txt - It doesn't works.
• Building and running with JDK 11 and after that, just running with JDK 13 log-java11-and-13.txt - IT WORKS!

[ignasi35]

I'll close this issue since JDK13 is not a supported platform yet.

[antonini]

Ok. Thank you.
Is it on the roadmap?

[dwijnand]

We'll probably target the next LTS after Java 11, which is Java 17 in September 2021.
