+To test against an early access version java version you can pass the major

+
+```
+./gradlew clean test -Druntime.java=26-ea

+in our custom jdk catalogue at `https://storage.googleapis.com/elasticsearch-jdk-archive/jdks/openjdk/latest.json`.
+
+To run against a specific build number of the EA build you can pass a second system property (e.g. `-Druntime.java.build=6`):
