I still believe HTML script tags aren't supported for rendering in Java's 
Parser. 

I have made a new local test. This test generates an HTML file that has an 
alert function within HTML script tags. An input button calls this alert 
function and generates a pop-up alert, and this works when the HTML file is 
opened in a browser.

When I open the same HTML file in a JEditorPane, the script tag itself is 
displayed along with its contents. The script tag is displayed in a directional 
text input field and its contents are within these boxes.

I looked into TagElement and HTML.java and "SCRIPT" is shown in the list of 
known tags, so that means "SCRIPT" is not labeled as an "Unknown tag" by the 
parser, which I confirmed in testing.

I also looked into the strict flag, which enforces SGML compatibility, in 
Parser as @jayathirthrao suggested. With the flag set to true, the output to 
JEditorPane remains the same, but with no error logged. The normal sequence 
continues and the strict flag seems to mostly be associated with syntax issues 
such as extra spacing.
