I compiled grasscutter from latest dev branch.
And uses java 16.

[Scirese]

seems related to #136 CC @miyucchi

did he tested the pr before push?
At least make it working before push...

[KingRainbow44]

this issue comes from the PR, which was created presumably before the Java 16 merge.
someone will need to update this in another PR so this issue will remain open

[KingRainbow44]

the issue itself is trivial to fix, add @Entity above the class declaration for PlayerBirthday

[shiroruby]

@Scirese yes I tested it, but on JDK 8. Next time I'll use Java 16 to avoid these problems.
@MlgmXyysd Thanks for fix and sorry for a mistake. ;/

Not your fault, the dev branch was on java 8 when you made the pull request. Anyways, since it was fixed in #144, i will be closing this now.
