FULL PRODUCT VERSION :
Java 9.0.1

ADDITIONAL OS VERSION INFORMATION :
Windows 10 (Creators Update)

EXTRA RELEVANT SYSTEM CONFIGURATION :
Java Swing GUI application installed via the Windows Store (i.e. APPX package)

A DESCRIPTION OF THE PROBLEM :
The Desktop Bridge makes it possible to deploy Java Swing applications in the Windows Store. This worked for Java 8, but for the latest Java 9 there seem to be issues running in this environment.

e.g. opening JFileChooser deadlocks the Swing EDT and freezes the application, drag-n-drop not working, etc.

REGRESSION. Last worked in version 8u144

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Java Swing applications packaged with Java 9 and deployed on the Windows Store should work.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Exception in thread "Swing-Shell" java.lang.InternalError: Could not initialize COM: HRESULT=0x80010106
    at java.desktop/sun.awt.shell.Win32ShellFolderManager2.initializeCom(Native Method)

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
Creating a test case would take a few hours. I will create one if it's necessary.

CUSTOMER SUBMITTED WORKAROUND :
Using Java 8 works fine, but we need Java 9 for HiDPI support.
