It looks like you are missing an import statement in one of the tests:

> Task :systemTests:compileTestJava
...\jfx\tests\system\src\test\java\test\javafx\scene\InitialNodesMemoryLeakTest.java:88: error: cannot find symbol
        JMemoryBuddy.assertCollectable("groupWRef");
        ^
  symbol:   variable JMemoryBuddy
  location: class InitialNodesMemoryLeakTest

1 error

You can run the following locally on your system once you have fixed this to verify that there are no others.

gradle --continue -PFULL_TEST=true test
