29 introduced a set of GitHub actions testing the library against multiple Java versions. It turns out that this doesn't work as expected. The version specified in build.gradle is automatically downloaded when not available on a machine, thereby the JAVA_HOME environment variable is ignored. As a result, the Java versions provided by the GitHub actions aren't used. This PR should fix this issue.
