> By default wsdl2Java is coded to use 128M of maximum memory heap space.
> These days, however, WSDLs are starting to become very large and complex beasts - and sometimes wsdl2java will run out of heap space while creating its internal data structures. This is not an issue with memory management within wsdl2java, but rather a consequence of large WSDLs.
> Because of CXF-2081, we have the ability to set the maximum memory heap size, however it requires manually modifying wsdl2java. This is not ideal. 
> This JIRA is requesting two things:
> a) A command line option -Xmx to wsdltojava, that allows users to set the maximum heap memory size.
> b) Upping the default maximum heap memory size to 256M. I leave this up to the development team to decide.
> UPDATE:
> Another option is for wsdl2java to inherit all the JAVA_OPTS from the environment. So, if someone properly sets -Xmx in the environment variable JAVA_OPTS, wsdl2java will pick it up. This is probably a better solution that will address more use cases.
