Package: tomcat5
Version: 5.0.30-12
Apache ships tomcat 5.0.30 with ant 1.6.2, while Debian Etch has ant
1.6.5 installed system wide.
On two different Etch installs, I had the following problem occuring
when accessing JSP files that needed to be compiled:
org.apache.jasper.JasperException: Unable to compile class for JSP
org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:520)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:295)

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

root cause

A restart of tomcat would normally fix the problem, but then other pages
would start having this seemingly random problem.
Downgrading to ant 1.6.2 from oldstable fixed the problem completely.
This looks like a bug in either Ant or Tomcat. I would suspect Ant,
since the problem is that a NULL key is inserted into a Map inside the
ant code base, which should be checked for.
