Just check the English API specification page:
http://java.sun.com/j2se/1.5.0/docs/api/javax/crypto/KeyAgreementSpi.html
or
http://download.java.net/jdk6/doc/api/javax/crypto/KeyAgreementSpi.html

You will see "(@see #engineDoPhase(java.security.Key, boolean) engineDoPhase)", but, this string should be link which link to "engineDoPhase" method, instead of the plain text.

so we need update the source file: j2se/src/share/doc/stub/javax/crypto/KeyAgreementSpi.java
in which: "(@see #engineDoPhase(java.security.Key, boolean) engineDoPhase)" need be updated to:
"{@link #engineDoPhase(java.security.Key, boolean) engineDoPhase}"
