Starting type  JSP comment tag <%-- inside <script> tag leads to insertion of two hyphens just before closing </script> tag. When it happens in big long pages no one can spot it the moment it happened, and finally hit by unexpected javascript syntax errors in runtime.

Reproducible: Always

Steps to Reproduce:
1. Open example JSP file attached and place cursor on line 21.
2. Type JSP comment tag "<%--" (without quotes) symbol by symbol. Keep your eye on closing </script> tag.
3. After typing past hyphen you see two hyphens "--" just before closing script tag.

This happens if there is at least one Java code included between <script> and </script>, see lines 26-28 of the example source code. Remove these lines and this behaviour disappears.
