Version 2.7 in Maven Reactor may cause infinite recursion, symptoms similar to MJAVADOC-268
-------------------------------------------------------------------------------------------

                 Key: MJAVADOC-286
                 URL: http://jira.codehaus.org/browse/MJAVADOC-286
             Project: Maven 2.x Javadoc Plugin
          Issue Type: Bug
    Affects Versions: 2.6
         Environment: Apache Maven 2.2.0 (r788681; 2009-06-26 15:04:01+0200)
Java version: 1.6.0_13
Java home: /home/mkleint/javatools/jdk1.6.0_13/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux" version: "2.6.29.6-desktop-2mnb" arch: "i386" Family: "unix"
            Reporter: Parag Mehta
            Assignee: Vincent Siveton
            Priority: Critical
             Fix For: 2.6.1


The getModulesLinks() method is unacceptably slow under certain conditions:
1. project's url is defined
2. one or more projects in reactor do not have any java sources and are not of "pom" packaging.
For such projects the apidocs/ output folder is never created resulting in repeated invokation
of a forked javadoc goal. It's more severe with high number of modules in reactor and high
number of modules without any java sources.

as an example checkout "hg clone https://hg.kenai.com/hg/forceten~src"

The immediate problem is in the apidocsFile.exists() condition that re-triggers the forked
invokation. The attached patch fixes that. However it looks suspicitions that the method is
being called repeatedly for each module at all. Maybe the aborting condition at the start
of the method body is wrong (I was not able to decypher that)

workaround is to use 2.5 or not to specify the url in pom.xml or set the detectOfflineLinks
parameter to "false".
