I have previously used envinject versions 1.13 and 1.17.
envinject always had problems with UNC paths in Windows.
(ex. MY_SHARED_FOLDER=\\MYCOMPUTER\Shared)
I previously was able to escape these directories by using double slashes
(MY_SHARED_FOLDER=\\\\MYCOMPUTER\Shared).
However, one of the updates between 1.17 and 1.20 introduced functionality that updates the the "Properties Content" each time the config page is saved. So after I set my value to "\\\\", and save. If I load the page again, the value is set to "
". If I save and load again, this becomes "\".
This is a very serious issue that forced me to downgrade the plugin even though I really want the Mask Password fix.
