SQL developer error with "disable modules and continue"

I just deleted eveything from

C:\Users\Bopsi\AppData\Roaming\SQL Developer\system4.0.2.15.21

and it worked.

I came across this problem when I was switching my Java version back and forth from J8 to J11. Resolutions with deleting whole systemX.X.X.X.X or .sqldeveloper aren't good, because you'll loose all your settings (saved connections etc.).

What worked for me was just deleting system_cache folder. I had version 19.2.1.247.2212, so it was:

rm -r ~/.sqldeveloper/system19.2.1.247.2212/system_cache/
