build failure

[Jonathan Lu]

Hello Richard,

I've got similar problems, to be more specific, I was playing with the code from
http://hg.openjdk.java.net/nashorn/jdk8/nashorn   on a Windows 7, 32bit box and following the instructions from the README file.

OpenJDK 1.8.0-b77 downloaded from official snapshot website was used as bootstrap JDK, the build process will stop on the "javadoc" target of nashorn/make/build.xml with a lot of errors, most of which are about parsing javadocs (of course).

like

   [javadoc] D:\nashorn8\nashorn\src\jdk\nashorn\internal\codegen\ClassEmitter.java:80: error: tag not allowed here: <p>
   [javadoc]  * <p>
   [javadoc]    ^
   [javadoc] D:\nashorn8\nashorn\src\jdk\nashorn\internal\codegen\ClassEmitter.java:84: error: tag not allowed here: <p>
   [javadoc]  * <p>
   [javadoc]    ^
   [javadoc] D:\nashorn8\nashorn\src\jdk\nashorn\internal\codegen\ClassEmitter.java:91: error: tag not allowed here: <p>
   [javadoc]  * <p>
   [javadoc]    ^
   [javadoc] D:\nashorn8\nashorn\src\jdk\nashorn\internal\codegen\ClassEmitter.java:95: error: tag not allowed here: <p>
   [javadoc]  * <p>
   [javadoc]    ^

One simple workaround I have to use is to set useexternalfile="yes" for javadoc ANT task, otherwise there'll be a error reporting too long filename, see the diff below:

        <classpath>
          <pathelement location="${build.classes.dir}"/>
        </classpath>

The actual problem is that OpenJDK8-b73 would make the build pass, but OpenJDK8-b77 failed.
So I was guessing some recent introduced changes lead to this problem. Will continue to look into it and update this thread once got any progress, if anybody has got a clue about the recommended bootstrap JDK or experiences of building on Windows platform, it would be very helpful and welcome.

Thanks a lot and best regards
