Exception Access Violation causing jvm crash after updating flatlaf version to 3.1(3.1.1)

[liucunjie]

Our program works fine on flatlaf v3.0, But jvm crash occurred after updating to 3.1 or 3.1.1. I can't pinpoint the problem. Any ideas are appreciated.
OS：windows 10
JVM: 1.8

Strange that it works with FlatLaf 3.0 but crashes with 3.1 because there is actually nearly no changes in native code regarding window decorations from 3.0 to 3.1. Only added new native methods. See commit 07ad467#diff-0393d6d30e320a47e5a348543e9382b73ddee2bfa56889beb3c9d4c88a3be8fd

And the used JRE and PC are the same in both cases?

Does it work with Java 11 or any other newer Java version?

Thank you for giving suggestion. Thanks a lot :)
It worked after upgrading jre 8 to 11

Yes, all the test on the same JRE and PC.

Finally was able to reproduce the crash 😄

Occurs under following conditions:

• on Windows 10/11
• and application runs in Java 8 (but older than 8u321)
• and newer Java version (e.g. 11) is installed and added to PATH environment variable
• and using class SystemInfo before AWT initialization

The problem is that awt.dll from Java 11+ is loaded, via PATH variable, into Java 8, which causes the crash.

This can be seen in your log where awt.dll is loaded from Eclipse JRE 17 and from Java 8:

Here is the PATH from your log:
