Describe the Issue

With GraalVM 25.2.4, native-image -Werror fails even for a trivial Hello World application.

The Native Image driver passes:

-H:DriverWarningsCount=2

to the image builder, and the build finishes with:

The build process encountered 2 warnings.

Error: Build failed: Warnings are treated as errors because the -Werror flag is set.

However, no Warning: messages are printed during the build, including when --verbose is enabled.

The issue reproduces with both:

  • GraalVM Community Edition 25.2.4+7.1
  • Oracle GraalVM 25.2.4+7.1

It reproduces when invoking native-image directly, without Gradle, Kotlin, Maven, or any third-party dependencies.

Using the latest version of GraalVM can resolve many issues.

GraalVM Version

openjdk version "25.0.4" 2026-07-21
OpenJDK Runtime Environment GraalVM CE 25.2.4+7.1 (build 25.0.4+7-jvmci-25.2-b20)
OpenJDK 64-Bit Server VM GraalVM CE 25.2.4+7.1 (build 25.0.4+7-jvmci-25.2-b20, mixed mode, sharing)

The same behavior was also reproduced with Oracle GraalVM 25.2.4+7.1.

For comparison, Oracle GraalVM 25.0.4+7.1 does not recognize -Werror and does not print the warning-count summary.

Operating System and Version

Microsoft Windows [Version 10.0.26300.9032]

Build Command

javac Hello.java

native-image --verbose -Werror -cp . -o Hello Hello

Expected Behavior

Either:

  1. the build completes successfully if there are no warnings; or
  2. if two warnings actually occur, their messages are printed and -Werror fails the build because of those visible warnings.

For this trivial application, I would expect the former.

Actual Behavior

The image itself is generated successfully, but Native Image reports two warnings only by count and subsequently fails because of -Werror.

The verbose driver invocation contains:

-H:DriverWarningsCount=2

No corresponding Warning: messages are printed before this.

At the end of the build:

Build artifacts:
 C:\w\testGraalDriverWarnings\Hello.exe (executable, 5.00MiB)

Finished generating 'Hello' in 11.0s.

The build process encountered 2 warnings.

Error: Build failed: Warnings are treated as errors because the -Werror flag is set.

Steps to Reproduce

Create Hello.java:

public class Hello {
    public static void main(String[] args) {
        System.out.println("Hello");
    }
}

Compile it:

javac Hello.java

Build the native image:

native-image --verbose -Werror -cp . -o Hello Hello

Observe that:

  1. no Warning: messages are emitted;
  2. the verbose builder invocation contains -H:DriverWarningsCount=2;
  3. the executable is generated;
  4. the command nevertheless exits with an error because -Werror sees two warnings.

Additional Context

The same minimal reproducer produces the same DriverWarningsCount=2 with both GraalVM CE 25.2.4+7.1 and Oracle GraalVM 25.2.4+7.1.

I also tried setting:

NATIVE_IMAGE_EXPERIMENTAL_OPTIONS_ARE_FATAL=true

and running the build without -Werror. The build still completes and reports two warnings, so these do not appear to be illegal experimental-option warnings.

Possibly relevant changes:

  • 9795ca57e60560229004a168f2c28ef532a1fdda
    • "track warnings in Native Image build and list their count at the very end of the build"
  • 6a75f11bfa63e8ccf6c0eaf2e605cd6d8673404f
    • "add option -Werror to fail when a warning occurs"

I am not sure whether the initial value of the warning counter is the root cause, but these changes appear related to the observed behavior.

Recommendations:
 FUTR: Use '--future-defaults=all' to prepare for future releases.
 HEAP: Set max heap for improved and more predictable memory usage.
 CPU:  Enable more CPU features with '-march=native' for improved performance.
