#17 NullPointerException when clicking in editor

[Pierre-Yves B.]

Hello,

I've just updated to version 0.5.1.202008061148 of the plugin, and I'm seeing the following exception when clicking in different parts of the editor. Note that I'm using version 4.17.0 M1 of Eclipse.

Hello,

this should be fixed with 0.5.1.202008080125.jar.

The problem is being compatible with the version SWT version 4.335 from 2014-02-02 and the new versions used in Eclipse 4.x. I've fixed the wrapper class which now perform dynamic calls to use methods as the are available in the environment. Tested in standalong and Eclipse 4.16.

Best regards, Peter.
