Jasper compile behavior change?

[Ellis Teer <e_...@yahoo.com>]

Question about the JSP engine in Tomcat 4.0b6...

I have a JSP file which compiled and ran under previous non-4.0 versions of
Tomcat.  When the container tries to compile JSP files with lines like the
following....

<%= (checkOn)?" bgcolor=\"#99cc99\"":"" %>

Errors are generated which look like the following (slightly edited)...

____________

A Servlet Exception Has Occurred
org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 451 in the jsp file: foo/foo.jsp

Generated servlet error:
C:\network\jakarta-tomcat-4.0-b6\work\foo\_0002ffoo_0002ffoo_jsp.java:1039:

                out.print( (checkOn)?" bgcolor=\\"#99cc99\\"":"" );

It looks like Jasper is escape coding my backslashes.  Previously those
backslashes were to escape code the quotes.  Is the container supposed to
escape code all \ and " characters when using the <%=  %> command?  Is this new
bahavior/spec revision/a bug?
