Team,
I have installed openjdk 11 (11.0.16) in RHEL servers using yum install. But when I tried to use Gradle (6.8/7.5) getting the below exception.
java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$PlatformClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$PlatformClassLoader and java.net.URLClassLoader are in module java.base of loader ‘bootstrap’
Please let me know how to resolve this issue
You should provide the command you do and the stacktrace to see where the error comes from exactly.
Iirc PlatformClassLoader used to extend URLClassLoader in older Java versions but then changed in Java 11 or so.
So something you use is not Java 11 compatible, but I guess this is coming from the build script or some plugin.
Below is the java version installed in RHEL Server
java -version
openjdk version “11.0.16” 2022-07-19 LTS
OpenJDK Runtime Environment (Red_Hat-11.0.16.0.8-1.el7_9) (build 11.0.16+8-LTS)

Gradle command used:

Hm, from a quick look I’d say that there indeed is an incompatibility in Gradle.
Maybe the RedHat built Java is different in that respect from other Java builds.
I’d recommend you open an issue on Gradle’s GitHub and as a work-around try to use a different Java runtime.
