Have you ever faced an error while launching Apache Directory Studio ? I faced this error recently on my MAC OS. Problem: I was using Apache Directory Studio for past few months without any issues, but yesterday all of a sudden I was getting below error while I was attempting to launch Apache Directory Studio application on my MAC. Note that I am using Apache Directory Studio version 2.0.0.v20130628 I open the log file to check the error message, it was so confusing. Error message was something like this: Root Cause: I recently installed latest Java version i.e. Java 9 on my MAC and I encountered this issue due to the Java version upgrade.

After installing AnypointStudio, when I opened it for the first time, I immediately encountered an issue. Guess what, the very first screen - Workspace Launcher was frozen. I was not able to type-in workspace location, I was not able to click on browse button, I was not able to click on cancel or ok button. What a bummer!! After some trial and errors, I finally found the solution to fix the problem. I am not sure why, but looks like Anypoint Studio does not work with Java 9. As part of upgrade process, I had upgraded the Java version from 7 to 9. Either you will have to uninstall Java 9 and go back to Java 7 (I did not test this with Java 8) or you can follow below steps to make it work. Install Java 7 in addition to Java 9 on MAC OS. Get the Java 7 location, we will need this location....
