Illegal reflective access warning on Classpath.getClasspathURIs() with Adopt JDK 11

I use AdopJDK on Windows with the following version:

Eclipse OpenJ9 VM AdoptOpenJDK (build openj9-0.24.0, JRE 11 Windows 10 amd64-64-Bit Compressed References 20210120_899 (JIT enabled, AOT enabled)
OpenJ9   - 345e1b09e
OMR      - 741e94ea8
JCL      - 0a86953833 based on jdk-11.0.10+9)

With ClassGraph 4.8.135 I have a JEE application running in Open Liberty that does the following ClassGraph call:

List<URI>       classpathEntries = new ClassGraph().getClasspathURIs();

With this I get the following warning from the JDK:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by nonapi.io.github.classgraph.reflection.ReflectionDriver (file:/D:/Programme/openLiberty/openLiberty-SAMV/wlp/usr/servers/SAMV-Liberty/apps/expanded/Gradle___de_dsv_samv___SamvEAR_ear.ear/lib/classgraph-4.8.135.jar) to method com.ibm.java.lang.management.internal.RuntimeMXBeanImpl.getInputArguments()
WARNING: Please consider reporting this to the maintainers of nonapi.io.github.classgraph.reflection.ReflectionDriver
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

As the warning mentions that illegal reflective access might be denied in future releases of the JDK it would be interesting how to handle this situation.

Your are right. Seems to be a problem with my environment. The correct version is selected from Gradle.

Great, thank you for confirming!

I have no idea where Gradle looks up the latest version. Is this a Gradle thing, or a Gradle IDE plugin thing?
