Hello,
I have installed the new version 18.1 of SQL Developer on Oracle Linux 7.
After first install I closed the sqldeveloper but when trying to start it again it starts and when finished it crashes immediately.
tried uninstall and reinstall but still the same.
after uninstall and install of the previous version 17.4 - It starts fine. this means that something is wrong with the new Linux version of sqldeveloper.
