Subject RE: Found the problem with the different behavior between NT and Unix

I don't think I have ever seen 8.3 names come back from
getCanonicalPath().

I did a quick test with JDK 1.3 and Tomcat 3.2 installed at
"D:\Jakarta Test\jakarta-tomcat".  getCanonicalPath() returned
the full non-8.3 names in FileUtil.safePath().

I have also run Watchdog against Tomcat (both tomcat_32 branch)
in the above directory with JDK's 1.3, 1.2.2, and 1.1.8.
Everything passes except for a few tests with JDK 1.1.8, where
the path to the JSP's servlet source goes over 256 characters.  

I don't know why 8.3 names are being returned is your case.
Which JDK are you using?

Larry
