I was trying to work on my Mac and found out that JDev (12.2.1) won’t start up. It will try, but eventually will just go away and not open up. I found a very helpful blog post from Ilan about it, but wanted to re post it in a more visual and detailed way.
So this is the only glimpse I could get from my IDE:
I then tried opening it from <ORACLE_HOME>/jdeveloper/jdev/bin/jdev to check the logs and found the following error:

So the only thing that needs to be done is to delete the system_cache folder located in <HOME>/.jdeveloper/system12.2.1.0.42.151011.0031/system_cache, in which HOME is where the jdeveloper and mywork folders with all our projects are. This was my case:
Then we can just try to open JDev again and start having fun.
