OutofMemoryError running Ejbdoclet

I posted the below to the Ant mailing list as well and one suggestion was to try and fork the ejbdoclet task.  I found several issues on the Xdoclet mailing lists that seemed like a match but were either not fixed or not quite the same issue.  I am not running inside an IDE, which several issues mentioned.  One issue (several years old) mentioned using the maxmemory parm on my task tag but apparently that parameter is no longer accepted – it was found in the ‘olddocs’ on the sourceforge site.

 

Is there a way to ‘fork’ the ejbdoclet task?

How do I get the functionality of the apparently old ‘maxmemory’ parameter for the ejbdoclet task?

 

I am trying to resolve an OutOfMemoryError within our build process.  We have a work-around but would really like to be able to run our ‘standard’ targets to get everything built.  We have a 3 layer file structure for components, modules then submodules.  Our compile target is compile.all.all which calls compile.all for the the modules, which then calls compile on the submodules, using subant.

 

Software version/levels: Ant 1.6.2 (or 1.6.5), JDK 1.4.2_08 and XDoclet 1.2B4

 

Have set ANT_OPTS=-Xmx1024m and our compile tasks use fork=”true”.  

 

I also included a call to a java task that calls the Runtime class to get the memory values in hopes that it might provide some assistance.  I placed this before the javac and the ejb tasks (which calls ejbdoclet).  Below is the output just before the failure in the ejbdoclet task.  I have run the failure with both –v and –d but nothing jumps out at me as significantly wrong – but then again – I am not an Ant expert!

 

The error seems to be coming when we run the ejbdoclet task

 

Looking for suggestions and any assistance!   Thanks in advance.
