Description

When using JClouds BlobStore for Google Cloud Storage with Java 11, some warning are displayed by the JVM about illegal reflective access:

 

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.jclouds.reflect.Reflection2$1 (file:/.../jclouds-core.jar) to constructor java.lang.String(char[],int,int,java.lang.Void)
WARNING: Please consider reporting this to the maintainers of org.jclouds.reflect.Reflection2$1
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

 

JClouds works but as stated, these illegal reflective accesses may be denied in upper Java versions.
