Thanks for the report.

All tests pass in Java 8, which is what the project targets. I can see this failure with Java 14, but upgrading to Java 14 isn't something we're likely to work on, and I don't know how complicated any required changes would be.

Actually that was tested with:

java -version
openjdk version "11.0.8" 2020-07-14
OpenJDK Runtime Environment (build 11.0.8+10-post-Ubuntu-0ubuntu118.04.1)
OpenJDK 64-Bit Server VM (build 11.0.8+10-post-Ubuntu-0ubuntu118.04.1, mixed mode, sharing)

The error occurs in https://github.com/gbif/gbif-common , which also has in pom.xml
<jdkLevel>1.8</jdkLevel>

So its'likely that all dependent modules should be upgraded together.

It's not blocking for me, I can use the library .

surprisingly I get the same if I run maven with java11 and do a clean build with mvn clean compile test

[mdoering]

I suspect some included library is compiled with an older java version? gbif-common 0.45 maybe? Ive updated to the latest versions locally, but no difference

[jmvanel]

It's possible that compiling gbif-common with java11 fixes most of the 17 errors .
