---------------------------------
    Attachment: derby-6751-01-ab-usederbyinternals.diff

Attaching derby-6751-01-ab-usederbyinternals.diff. This version of the patch 
adds doPrivileged() blocks to some more callers of 
EmbedConnection.getLanguageConnection(). I am re-running tests now.


Touches the following additional files:

M       java/engine/org/apache/derby/impl/jdbc/ConnectionChild.java
M       java/engine/org/apache/derby/jdbc/EmbedPooledConnection.java
M       java/engine/org/apache/derby/jdbc/EmbedXAResource.java
M       java/testing/org/apache/derbyTesting/junit/BaseJDBCTestCase.java

> User code can cast a java.sql.Connection to an EmbedConnection and then get 
> the LanguageConnectionContext by calling 
> EmbedConnection.getLanguageConnection(). We should prevent user code from 
> doing this.
