Method Detail

init

public static AccessEnabler init(Instrumentation inst)

Create and return an AccessEnabler to manage enabling reflective access. For JDK8 and lower releases return a DefaultAccessEnabler which does not now about module encapsulation. For JDK9 and higher releases return a JigsawAccessEnabler which is capable of enabling access to members of classes which are normally inaccessible because of module restrictions. caveat: during testing class JigsawAccessEnabler may fail to load even thought the JDK is modular. That happens when testing that the JDK8- core classes work without the JDK9 code present. In this specific situation a DefaultAccessEnabler is returned. A helper trace message is logged just in case.

Parameters:

inst - an Instrumentation instance which may be needed enable access to members of unexported module classes

Returns:

an AccessEnabler to manage enabling reflective access
