Running PyCharm 2019.1.2 gives warnings on Ubuntu 18.04. Follow
Hi,
I've just installed PyCharm and running it gives the following warnings:
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.intellij.ide.ClassUtilCore to field sun.net.www.protocol.jar.JarFileFactory.fileCache
WARNING: Please consider reporting this to the maintainers of com.intellij.ide.ClassUtilCore
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release
Should we ignore these warnings?
Thanks for any help.

Thank you Sergey.
I have this error too on Ubuntu 18.04. Unfortunately, PyCharm doesn't open.
I'm using Fedora 30 and had the same error. The program just doesn't start.
Everyone who can't start their PyCharm, try a clean reinstall to the latest version: https://www.jetbrains.com/pycharm/download
