------------------------------------------

             Summary: Improving compliance to Java 5+
                 Key: OPENJPA-2439
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2439
             Project: OpenJPA
          Issue Type: Dependency upgrade
    Affects Versions: 2.3.0
            Reporter: Guillaume Chauvet


Hello,

I provide this patch to improve the compliant of OpenJPA to Java 5+.
Changes included in this patch are :
======
# Migrating from commons-lang to commons-lang3 :
Implies :
-> Removing call to NestedExceptions classes.Explanation from commons-lang homepage :
"In Java 1.4, the notion that all Throwables could be linked to a cause was introduced. In
Lang we had provided a NestedException framework to support the same feature, and now that
we're jumping from Java 1.3 to Java 5 we are remove this feature. The deprecation section
below covers one part of ExceptionUtils that remains until we are on Java 6, where the last
remaining parts of the JDK appear to have embraced the new cause API."

-> Replace package **.apache.commons.lang to **.apache.commons.lang3

# Migrating SLF4J artefact to 1.7.5 :
According to SLF4J news (http://www.slf4j.org/news.html) :
- Given the significance of these performance improvements, users are highly encouraged to
migrate to SLF4J version 1.7.5 or later.
- Removing dependencies to commons-lang2

# Migrating artefact org.apache.bval.bundle form version 0.3-incubating to 0.5 (removing direct
SLF4J 1.6.1 dependency that includes commons-lang2 dependency)

If this patch is approved, I will create a subtask for adding @Override annotation to all
java classes (maven-compiler plugin is configured to target bytecode version 1.5 and compilation
process is configured for 1.6).
