Overview:
Within the <script> block of a JSP file, if there are any JavaScript variable declaration added after "%>", the JSP is marked with a red error badge. On mouse-over the file name the tooltip shows "Error parsing file".

Steps to reproduce:
1. Create a new JSP file within a project.
2. Add a <script> block.
3. Within the <script> block add a scriptlet with:
<%
    if (true)
    {
%>var i = 0;
alert(i);
<%
    }
%>
4. Save the file.
5. Notice the red error badge on the file. Sometimes the editor window will also display a warning annotation on the "var" line.

Workaround:
Move "var" declaration to a new line (i.e. press ENTER after %>) and the parse error goes away upon save. I discovered this issue and workaround when reformatting a few JSP files but it may not be feasible to do so on a large web project (large number of JSP files).

Expected result:
There should not be any parsing error as it is not necessary to have a new line after %>.
