I wonder if enabling "Hide Network Locations icon on desktop" Group Policy causes this issue too. According to the description, it “removes the Network Locations icon from the desktop. This setting affects only the desktop icon.” The policy setting can be found at User Configuration -> Administrative Templates -> Desktop -> Hide Network Locations icon on desktop. Enabling the policy adds NoNetHood=1 value under HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer.

It needs deleting the registry from the system which might cause some problem. We need to find some test machine where we can perform this test and currently we do not have such machine. Postponing for machine availability to test this.

JDK 8u152 Windows 7 JFileChooser throws NPE when "My Network Places" is hidden from Windows Explorer view Tried to verified this with the provided steps, however couldn't proceed. The reproducible steps involves deleting the registry keys from the system. Not sure, if we can consider this as a valid request. Actual reproducible steps: ======================== 1. Hide "My Network Places" from Windows Explorer view https://blogs.technet.microsoft.com/csstwplatform/2010/05/05/how-to-hide-my-network-places-from-windows-explorer-view/ 2. Execute test case ========================= Writing back to the submitter to understand the context about these steps/issue?

Additional information from the submitter: ======================================= - Actual steps to reproduce the issue. Explain why do you need to delete the registry keys which is not recommended under normal circumstances? Because "My Network Place" is hidden in my customer's environment. I have no authority to change customer's environment. Considers this as a Java issue, - Because sun.awt.shell.Win32ShellFolderManager2#getNetwork may return null, I think that should check null. ==============================
