Hello.
Please review the fix for jdk11.
Bug: https://bugs.openjdk.java.net/browse/JDK-8189604
Webrev: http://cr.openjdk.java.net/~serb/8189604/webrev.00
We have a cyclic dependency in Win32ShellFolder2$KnownFolderDefinition,
which can cause a deadlock if this class is initialized on "non-COM" thread.
1. - Static initialization of Win32ShellFolder2$KnownFolderDefinition
2. -- Win32ShellFolder2.getLibraries();
3. --- invoke Win32ShellFolder2.loadKnownFolders() on "COM-thread" and wait
4. ---- in the native call
env->FindClass("sun/awt/shell/Win32ShellFolder2$KnownFolderDefinition");
5. ---- deadlock. because initialization of KnownFolderDefinition was
blocked at step 3.
In the fix this dependency is broken, so the new class KnownLibraries is
not depends from its own initialization.

Best regards, Sergey.
