Recently installed PhpStorm 2017.2.4 on my Mac Pro (Sierra 10.12.6), Java version is (9+181).

Whenever I try to open a project, PhpStorm hangs.
I took a look at the log file situated in `/Library/Logs/PhpStorm2017.2`.
There are several NoClassDefFoundError happening, with a slice of NullPointerException.
Here are a few excerpts:

```
java.lang.NoClassDefFoundError: com/apple/eawt/AppEvent$AboutEvent
java.lang.NoClassDefFoundError: com/apple/eawt/OpenURIHandler
java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter
java.lang.NoClassDefFoundError: Could not initialize class com.intellij.credentialStore.kdbx.KdbxKt
java.lang.NullPointerException at com.intellij.openapi.wm.impl.ToolWindowManagerImpl.b(ToolWindowManagerImpl.java:1800)
java.lang.NullPointerException at com.intellij.codeInsight.daemon.impl.DaemonListeners$MyProfileChangeListener.a(DaemonListeners.java:519)

```

* I tried to change the target java version in the `info.plist` configuration file inside the PhpStorm package.
* I also followed [these instructions](https://stackoverflow.com/questions/35270187/webstorm-11-fresh-install-not-starting-in-mac-osx) in order to be able to start the application.
* Just to check I also installed Webstorm, which worked perfectly out of the box.

After doing some research, it looks like no one else is having this problem. I really need some inspiration, some crazy idea to try.

PS: I uploaded the log file [here](https://ufile.io/6fh5g) if anyone feels like wading through it.
