Amy Yang commented on OPENJPA-536:
----------------------------------
Thank you Albert.
I generated another patch which is the output of "svn diff
openjpa-kernel\src\main\java\org\apache\openjpa\meta\MetaDataRepository.java".
Hope you can review it.
And I executed "svn add" for test cases:
svn add
openjpa-persistence-jdbc\src\test\java\org\apache\openjpa\meta\Person.java
openjpa-persistence-jdbc\src\test\java\org\apache\openjpa\meta\Item.java
openjpa-persistence-jdbc\src\test\java\org\apache\openjpa\meta\Artist.java
openjpa-persistence-jdbc\src\test\java\org\apache\openjpa\meta\TestGetMetaData.java

openjpa-persistence-jdbc\src\test\java\org\apache\openjpa\meta\Person.java

A
openjpa-persistence-jdbc\src\test\java\org\apache\openjpa\meta\Artist.java

openjpa-persistence-jdbc\src\test\java\org\apache\openjpa\meta\TestGetMetaData.java
Please correct me if anything is wrong.
