When running JavaFX tests and apps with JDK 24, we now get illegal access warnings of the following form:
WARNING: A restricted method in java.lang.System has been called WARNING: java.lang.System::load has been called by com.sun.glass.utils.NativeLibLoader in module javafx.graphics (file:build/shims/javafx.graphics/) WARNING: Use --enable-native-access=javafx.graphics to avoid a warning for callers in this module WARNING: Restricted methods will be blocked in a future release unless native access is enabled With the current jfx master, I get 301 such warnings on my macOS system (see the `test.log` file attached to the JBS bug report). In order to avoid those warnings, and to avoid the eventual errors in the future, we need to pass one of the following two options when running test programs: * "java --enable-native-access=javafx.graphics,javafx.media,javafx.web" -- for unit tests in the web and systemTests subprojects, as well as in the generated `build/run.args` file * "java --enable-native-access=javafx.graphics" -- for all other unit tests With this patch, we are down to 5 such warnings on macOS (on Linux there are few more, but the reasons are the same). The remaining warnings are due to the following two issues: 1. We are making a native JNI call from javafx.swing, which we should not be doing. This is a JavaFX bug. The native library in question is loaded by the javafx.graphics modules, so the solution will likely be to move the native method call to somewhere in javafx.graphics and call that new method from javafx.swing. 2. We have two unit tests that use a custom `ModuleLayer` to load the JavaFX modules at runtime, after the test application is launched. In this case the "--enable-native-access" is ineffective. I suspect this is a JDK bug. I will file a pair of follow-on bugs for these. ------------- Commit messages: - Merge remote-tracking branch 'upstream/master' into 8339517-enable-jni - Add --enable-native-access in two tests that don't use run.args - 8339517: Add --enable-native-access flag when running tests Changes: https://git.openjdk.org/jfx/pull/1562/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1562&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8339517 Stats: 37 lines in 3 files changed: 32 ins; 0 del; 5 mod Patch: https://git.openjdk.org/jfx/pull/1562.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1562/head:pull/1562 PR: https://git.openjdk.org/jfx/pull/1562
