Interaction with org.freedesktop.Sdk.Extension.openjdk9 crashes pycharm

[linuxrider]

When running pycharm while openjdk9 extension is installed it crashes with:

Upon removal of the extension it runs normal.

This problem is apparently older as its mentioned by @phracek in #5 already.

fwiw there's a jdk10 release which may be worth testing with now.
