Hi Alan, regarding usage of class VM I get
'package jdk.internal.misc is declared in module java.base, which does not
export it to module java.sql'
Is there any concern to export it as well to module java.sql ?
And btw did you mean to use it like this, in the if ?
` if (callerCL == null || VM.isSystemDomainLoader(callerCL)) {
callerCL = Thread.currentThread().getContextClassLoader();
}`
