Cannot use the runtime compiler with OpenJDK 25

[boris-petrov]

Describe the issue
Using GraalVM 25 with OpenJDK 25 downloaded from https://jdk.java.net/25/ leads to:

[engine] WARNING: The polyglot engine uses a fallback runtime that does not support runtime compilation to native code.
Execution without runtime compilation will negatively impact the guest application performance.
The following cause was found: The VM does not support the minimum JVMCI API version required by Graal: 25+36 < 25+37-jvmci-b01.
Currently used Java home directory is /usr/lib/jvm/jdk-25.
Currently used VM configuration is: OpenJDK 64-Bit Server VM
Download JDK 25 or later.

Steps to reproduce the issue
Just use GraalVM 25 on OpenJDK 25.

Describe GraalVM and your environment:

• GraalVM version 25
• JDK major version: 25
• OS: Linux
• Architecture: x86_64

More details
Workaround:

set environment variable JVMCI_VERSION_CHECK=ignore
and set the VM option -Dpolyglotimpl.DisableVersionChecks=true

Sorry for the inconvenience!

I verified that the workaround, works and is safe. : 25+36 is actually identical with 25+37.
This will likely need to wait until 25.0.1 is released.
Please make sure you remove the workaround after that version is released.
