compiler limitation -- static { } block is too large -- need refactoring
------------------------------------------------------------------------

         Key: SPRING-95
         URL: http://jira.andromda.org/browse/SPRING-95
     Project: Spring Cartridge
        Type: Improvement
    Versions: 3.1RC1    
Environment: Win2KSP4, JDK1.5 (JRE, HOTSPOT JVM, build 1.5.0_01-b08), Ant 1.6.2, Maven 1.0.2. Intel P4 2.1GH, 2GB RAM.
    Reporter: Safaa Hashim
Assigned to: Chad Brandon
    Priority: Critical


The following is abstracted from the forum.androMDA.org, Project Generator topic area:

The project generator gave me the following error, which seems to be a size issue with the code generator in Andromda. I have a model with over 1300 objects and about 14,000 associations.

Input from Chad and Wouter:

That package is where utility classes are generated (that class is used by the Hibernate Criteria support). As this error seems to happen as well in large JSP files (when compiled into a servlet), its a compiler limitation, I think the only solution is to generate multiple instead of one big file...or generate a properties file and read in the configuration I have in there. So if you would, please file a JIRA issue in the Spring cartridge.

I think the problem is that the static { } block is too large, I've seen that behavior also within Websphere when the contents of a try/catch were lengthy

I'm pretty sure simply doing multiple static blocks instead of one will solve the problem, I've never heard of a thing such as a class file size limit

That's very probably the cause - there is definitely a limit (64K if I recall correctly and if it hasn't changed since JDK 1.3) on the size of the bytecode for a single method/constructor/initializer block. I've encountered this problem in another code generator (XMLC, generates presentation layer Java code from plain HTML/XML pages), and solved it by splitting large methods into multiple smaller ones which were then called in sequence.
