the same is true for EJB2 CMP, see following errors when resin started up:

Causes:

1. Java compiler limits max size of 64k byte code per method, read footnote 4 at the bottom of http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html [^]
2. the size of __caucho_afterCommit() increases as the number of fields in an entity increases.


My Fix (in com.caucho.amber.gen.EntityComponent.java):

I re-arranged the generation of __caucho_afterCommit(), the modified file is http://backhoe.ironplanet.com/download/resin/fix1440/EntityComponent.java [^]

I downloaded 3.1.s061026 some time ago, so my work is based on that version.
