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.
======================
java:compile:
[echo] Compiling to C:\cvs_work\i\core/target/classes

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.
