Created attachment 159276 [details] Installer offers JDK dirs to the user I have Fedora 23 x86_64 with latest updates and I did: dnf -y install java-1.8.0-openjdk-devel.x86_64 Then downloaded Netbeans 8.1 (Java only) and the installation program offered me the /usr directory as a default (see attachment). But this does not work, as JDK could not be found (see the second attachment). Older version of Netbeans did not offered bare /usr directory (IIRC). Proposed fix: Installer should not offer plain /usr directory.
Created attachment 159277 [details] The error message if /usr directory with JDK was picked
Also then I was unable to change correct directory in Tools - Java Platforms and make it work. It is possible that the installation was completely borked. Removing&installing again with another Java JDK directory fixes the problem.
