Wildcards of gerneric type of jdk5.0
In src editor, type java.util.Collections.java.util.Collections.max
the doc popup

is T max(Collection<T> coll, Comparator<T>comp)
not the really:
<T> T max(Collection<? extends T> coll, Comparator<? super T> comp)

still try:(my experience)
-----------
  public static CertPath createPath(String certPath) throws Exception {
    File certPathFile = new File(certPath);
    FileInputStream certPathInputStream = new FileInputStream(certPathFile);
    CertificateFactory cf = CertificateFactory.getInstance("X.509");
    try {
      return cf.generateCertPath(certPathInputStream, "PKCS7");
    } catch (CertificateException ce) {
      // try generateCertificates
      Collection<Certificate> c = cf.generateCertificates(certPathInputStream); // discuss this
      return cf.generateCertPath(new ArrayList<Certificate>(c));
  }
------------------

See the comment line (//discuss this)
According to the doc popup, I write down this line,
but compile it, the compiler give me a error:
-----
incompatible types
found   : java.util.Collection<capture of ? extends java.security.cert.Certificate>
required: java.util.Collection<java.security.cert.Certificate>
      Collection<Certificate> c = cf.generateCertificates(certPathInputStream);
1 error
-----

The really signature is this:
-----
Collection<? extends Certificate> generateCertificates
	    (InputStream inStream) throws CertificateException 
------	   

If no src file in hand, how to know it.
