Description

Netbeans 12.2 reports NullPointerException when editing many of tpl files (Smarty templates). It looks like the NPE is shown if the file contains an html <script> tag. If a file has no <script> tags and I add one then the NPE is immediately shown. I'm still beginning to use version 12.2 and so far I haven't noticed any problems this NPE causes in practical use apart from being an annoyance but I suppose it might break something I'm not aware of. This problem did not happen in 12.1.

The plugin manager says I have version 1.97 of Smarty Framework. The problem occurs both on Oracle Java 1.8 and on JDK 11.

Here is the exception:
