tomcat - Negative time from JSP compiler

Question

What might be causing an error like this? Javadoc for File.java says it will throw this exception if passed in a negative value. So the question is, why is jasper passing in a negative value. I looked for the jasper sources, but I didn't find ones that match exactly what I am running, the line numbers don't quite match up. The version I have sets the last modified time from File.lastModified, which should never return a negative value, according to the javadoc.

SEVERE: Servlet.service() for servlet jsp threw exception
java.lang.IllegalArgumentException: Negative time

...

UPDATE: I downloaded the sources for Tomcat and read through the sources. The relevant code from Compile.java is:

375   File javaFile = new File(ctxt.getServletJavaFileName());
376   Long jspLastModified = ctxt.getLastModified(ctxt.getJspFile());
377   javaFile.setLastModified(jspLastModified.longValue());

ctxt is a JspCompilationContext, which helpfully returns -1 by default if there are any errors, and File throws IllegalArgumentException from a negative argument. I still don't know why I'm getting an error, at least I know where the IllegalArgumentException is coming from.

I had the same problem with 7.0.27 when I was deploying applications from IntelliJ Idea with a trailing slash in application context - removing it worked for me
