Executable size regression in 21.1

[kirillp]

Describe the issue
My simple app compiled by graalvm-ce-java11-21.0.0 is 7500k executable
And if compiled by graalvm-ce-java11-21.1.0-dev - 8M executable

So executable is 500k size bigger, have no differences in source code.

Steps to reproduce the issue
Please include both build steps as well as run steps

Use trivial System.out.println(); program
Compile it using graalvm-ce-java11-21.0.0 and graalvm-ce-java11-21.1.0-dev

Describe GraalVM and your environment:

• GraalVM version

• GRAALVM_VERSION="21.1.0-dev" JAVA_VERSION_DATE="2021-01-19"

• GRAALVM_VERSION="21.0.0" JAVA_VERSION="11.0.10"

• JDK major version: 11

• OS: Windows

• Architecture: AMD64

@kirillp please provide the reproducer

[kirillp]

What is not clear?
To reproduce compile a trivial single line program.
System.out.println(); with 21.0 and 21.1

I assume this is reproducible with the hello world:

public class Main { 
  public static void main(String[] args) {
     System.out.println("Kirill, is this it?"); 
  }
}

@kirillp please confirm if that's the case, thank you.

Right, the issue here is that we see +500k grow in executable size

FWIW - there's a similar discussion going on right now related to this here #3422. I see that you created this issue on 15 March and were using 21.1.0.dev version. The commit/change which is being discussed in the other issue was done on March 10, so it's likely that what you are seeing here is the same as what's being discussed in that other issue.

I see a 3MB increase when upgrading babashka to 21.1.0.

The diff shows that classes from sun.security.pkcs11, javax.security.auth, sun.security.util are being pulled in extra.

Closing this older ticket. Note we now have the -Os argument to optimize for size, if that is your main pain point. https://www.graalvm.org/jdk23/reference-manual/native-image/guides/optimize-for-file-size/
