FULL PRODUCT VERSION :
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)


FULL OPERATING SYSTEM VERSION :
Windows 98 SE

A DESCRIPTION OF THE PROBLEM :
When you open a URL connection to a directory using 'file:'
protocol, you get the wrong content-length header. The
problem is in
sun.net.www.protocol.file.FileURLConnection.java.
Line 96 reads (method initializeHeaders()):
  properties.add(CONTENT_LENGTH, TEXT_HTML);

instead it must be
  properties.add(CONTENT_TYPE, TEXT_HTML);

Moreover, if you call getContentType() on the
FileURLConnection before doing getInputStream() it will not
initialize the headers and will return the wrong value.

EXPECTED VERSUS ACTUAL BEHAVIOR :
getHeaderField("content-length") should return the length
of the stream or -1 but not the conten type ;)

This bug can be reproduced always.

System.out.println("type1 "+uc.getContentType());
System.out.println("len "+uc.getContentLength());
