In some rare situations DbVisualizer (Java) crash with macOS. The following are the scenarios we've got reported from users and the workaround last.

Scenario 1. Clicking a scrollbar

Clicking a scrollbar in DbVisualizer with Java 8 on macOS El Capitan causes the application (Java) to crash miserably.

Scenario 2. Starting DbVisualizer

Installing works fine but when starting DbVisualizer it crash immediately with a log as follows:

Other Java applications are also affected by this problem.


The solution is to install Java 6 which is not directly used by DbVisualizer itself but seems to fix the macOS environment for Java in general.

  1. Download Java 6 here: 
  2. Open the javaforosx.dmg file and install it
  3. Restart DbVisualizer
