Out of memory when turning on RMI generation

[pelakh]

Eclipse 3.0.1 on Windows XP, RMI Plugin 1.6.1.2. I just installed the plugin for the first time, to see if it would work with this source base. When I turn on generation for my project, the rebuild gets to about 61%, and then complains of an 'OutOfMemory' exception. I am already running with -Xmx on a 1GB system, and the project is not THAT large.

Here are the contents of the .log file for the session:

Is it possible that you use very large libraries?

Do you experience similar problems with other JDT tools, such as
hierarchy generation?

RMI Plugin does not allocate much memory and does not have large persistant state.

Please provide some numbers about your project, so I can try to estimate the possible effect on the RMI Plugin.

I do have a few JARs, and OpenMap is quite large. Though I have not experienced any problems with any other JDT tools.

Please provide some numbers about your project, so I can try to estimate the possible effect on the RMI Plugin.

How could I do this? What kind of numbers, and how could I extract them? Would it help if I broke up my project into several projects, with references?

I have just upgraded to 3.0.2 and 1.6.2, and wanted to try it again, but my 30-day license has expired. Is there a way for me to try it again - I don't want to purchase a license if I cannot get it to work. OTOH, we are transitioning a large group of people from JBuilder to Eclipse, so there are possibilities of a site license if the problem can be resolved.

Hi,

Breaking a project into several smaller projects should help. Yet it depends on the number of classes RMI Plugin has to consider in order to detect all remote classes.

Can you please email me the number of classes in your project?
How many Jars you use? How large (KBs) they are?

What are your memory settings? Do you pass any -Xmx switch to the java executable that runs Eclipse?

Best Regards,
Genady

I was able to get things to work by breaking up the project into 4 separate projects (only one of which has RMI), and increasing -Xmx to 1GB.

I am now the happy owner of a RMI Plugin license - thanks for your help.

Cool!
