Subject [jira] [Resolved] (OPENJPA-2085) Improve enhancement process to support JAVA 7 compliant class file generation
Date Sat, 03 Dec 2011 03:09:41 GMT

     [ https://issues.apache.org/jira/browse/OPENJPA-2085?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Albert Lee resolved OPENJPA-2085.
---------------------------------

    Resolution: Fixed

Use of ASM is one solution to implement the support. When Serp is enhanced to support the
same function, it can be be switched back to use Serp exclusively for the enhancement process.

> Java 7 requires StackMapTable attribute to be set in class file for verification.
> Serp does not support StackMapTable generation, hence the currently enhanced PersistenceCapable
class will NOT be able to load by a Java 7 JVM if the entity is compiled with a Java 7 compiler
(i.e. class file major version >= 51)
