Herve Boutemy commented on MJAVADOC-308:
----------------------------------------

IMHO, you should try to run javadoc by hand: I don't really see how this can be a Maven bug causing OOME in javadoc, and what Maven Javadoc Plugin can do

did you try configuring the plugin to give javadoc more memory?

> 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.
