Can't upload .html files (fileUpload: allowedExtensions)

Problems and solutions
1

I just ran into an issue while uploading a .html file in the assetmanager.

My Lucee version is Railo 5.4.3.16 Error (yes, the error template still says Railo).
And the error logged is:

Message:	Upload of files with extension [html] is not permitted.
Detail:	You can set a [allowedExtension] and a [blockedExtension] list as an argument/attribute with the tag [cffile] and the functions [fileUpload] and [fileUploadAll]. In addition you can configure this via the Application.cfc, [this.blockedExtForFileUpload] property, the [lucee.upload.blocklist] System property or the [LUCEE_UPLOAD_BLOCKLIST] Environment variable to allow this type of file to be uploaded.

The issue here is: FileUpload() :: Lucee Documentation
There’s a new attribute allowedExtension, but somehow the option is already in Lucee 5.4, not as announced in 6.0.

I can manage this easily, just wanted to point this out as hint for others.

Curious! Not run into that one before

The super simple solution to this:
application.cfc:
this.blockedExtForFileUpload="asp,aspx,cfc,cfm,cfml,do,jsp,jspx,php";

Additional pitfall: after setting the value, getApplicationSettings() still returns the variable as empty (NULL)
