Jörg Hohwiller commented on MJAVADOC-308:
-----------------------------------------
I diffed the options and packages file for both variants (mvn site vs. mvn
javadoc:javadoc).
* packages has no difference at all
* options has two differences: Prefix "JavaDocs for " is added to -doctitle and
-windowtitle
It gets even more insane: If I copy the options and packages files of "mvn
javadoc:javadoc" to a backup and after success of "mvn javadoc:javadoc" I copy
them back to the apidocs folder and manually invoke the javadoc tool like above
then I also get the error.
> OutOfMemoryError

> Key: MJAVADOC-308
> URL: https://jira.codehaus.org/browse/MJAVADOC-308
> Project: Maven Javadoc Plugin
> Issue Type: Bug
> Affects Versions: 2.6.1, 2.7
> Environment: Maven 3 on MacOS 10.6, Maven 3 on Hudson on Windows
> Reporter: Pieter
>
> I have a 12 module project (+parent) containing not really much code (140
> classes). When running Maven site on this project, it fails with an
> OutOfMemoryError. When I run the javadoc plugin with a reportset containing
> javadoc, test-javadoc and aggregate is runs well with a maximum heap size of
> 512M. When I run it with a reportset containing javadoc, test-javadoc and
> test-aggregate also. But when I add all 4 reports to my report set, I get an
> OutOfMemoryError, even when setting the maximum heap size to 1.5G. Just
> before the error occurs I see my heap usage growing rapidly.
