Describe the issue
A clear and concise description of the issue. We recommend using the latest snapshot builds to replicate the issue as bugs are constantly being fixed in the master branch

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

  1. git clone https://github.com/chiangzeon/graalvm_webflux_r2dbc_demo.git
  2. import to the jetbrain idea
  3. run native-maven-plugin native:compile
  4. run the exe file
    Describe GraalVM and your environment:
  • GraalVM version (latest snapshot builds can be found here), or commit id if built from source: [e.g. EE 19.3, CE 20.0, CE 20.1.0-dev-20200304_0848]
  • JDK major version:Oracle GraalVM 24.0.1+9.1 (build 24.0.1+9-jvmci-b01)
  • OS: Microsoft Windows 10 Professional
  • Architecture: x64-based PC

More details
I compiled the application into an exe file using the native-maven-plugin, but when running it, a DNS server not found exception was thrown.Here is the pom.xml and the error message. The database is MySQL. You can reproduce the issue by accessing any table through R2DBC.

Hi @chiangzeon,

Thank you for reaching out to us about this.

Can you please try initializing ResolverConfigurationImpl at runtime? you can do so using the following option:
--initialize-at-run-time=sun.net.dns.ResolverConfigurationImpl

你好@chiangzeon，

感谢您就此事与我们联系。

您能尝试ResolverConfigurationImpl在运行时初始化吗？您可以使用以下选项进行操作： --initialize-at-run-time=sun.net.dns.ResolverConfigurationImpl

Thank you for your reply. The problem has been solved.
