I'm currently using javadoc 1.3 to generate some documentation. It runs fine, no errors or warnings.

When I run Javadoc 1.4 Beta 2 using the same parameters and source files I get three warnings generated by three similar @see tags:

  warning - Tag @see: Class or Package not found: Throwable#printStackTrace
  warning - Tag @see: Class or Package not found: java.lang.Throwable#printStackTrace(java.io.PrintStream)
  warning - Tag @see: Class or Package not found: java.lang.Throwable#printStackTrace(java.io.PrintWriter)

The api javadoc is on my c: drive.

Any ideas?

Here's my javadoc parameters file contents:
       -d p:\java\javadoc -link c:\progra~1\jbuild~2\docs\api -sourcepath p:\java com.vincentosullivan.tools com.vincentosullivan.tools.test

There are no import statements in the source file. I've just tried adding

   import java.lang.Throwable;

to the source and running both versions of Javadoc. It made no difference to the results.
