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:
Invalid character in input.
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?
