Comments
These crash now because of a null sig_cc, so closing as a duplicate of JDK-8367408. No idea whether --enable-preview is now being passed to the subprocess as I thought was the bug.

I was looking into this and the JavacBenchApp needs --enable-preview to be passed to the compile command because --enable-preview is on the command line, but not sure how to get it to work. Attempt that requires some modules like: diff --git a/test/setup_aot/JavacBenchApp.java b/test/setup_aot/JavacBenchApp.java index a32069883af..8d5ea3cf989 100644 --- a/test/setup_aot/JavacBenchApp.java +++ b/test/setup_aot/JavacBenchApp.java @@ -41,6 +41,7 @@ import javax.tools.JavaFileObject; import javax.tools.SimpleJavaFileObject; import javax.tools.ToolProvider; +import jdk.internal.misc.PreviewFeatures; /** * This program tries to compile a large number of classes that exercise a fair amount of @@ -98,8 +99,16 @@ public Map<String, byte[]> compile() { DiagnosticCollector<JavaFileObject> ds = new DiagnosticCollector<>(); Collection<SourceFile> sourceFiles = sources; + // Add in preview mode if -Dtest.java.opts + List<String> opts = new ArrayList<>(); + if (PreviewFeatures.isEnabled()) { + opts.add("--enable-preview"); + opts.add("-source"); + opts.add("26"); + } + try (FileManager fileManager = new FileManager(compiler.getStandardFileManager(ds, null, null))) { - JavaCompiler.CompilationTask task = compiler.getTask(null, fileManager, null, null, null, sourceFiles); + JavaCompiler.CompilationTask task = compiler.getTask(null, fileManager, null, opts, null, sourceFiles); if (task.call()) { return fileManager.getCompiledClasses(); } else {

This still fails even with the CDS heap dump draft applied.
