Rob -
I have had a go at fixing them so jena-jdbc compiles on Java7. This is
done by adding missing operations, with no @Override, to the highest
abstract class I could find, usually JenaXYZ.java
All call SQLFeatureNotSupportedException
I've compiled with java6 and java7 compilers and runtimes, running "mvn
clean install".
I encountered problems running the tests -
with java6, the tests hang at:
org.apache.jena.jdbc.remote.results.TestRemoteEndpointResults
It completes on Java7.
Total time: Java7: 11:10.239s
Apache Jena - JDBC Parent ................[2.371s]
Apache Jena - JDBC Core API ..............[18.622s]
Apache Jena - JDBC Remote Endpoint Driver [4:32.039s]
Apache Jena - JDBC In-Memory Driver ......[11.076s]
Apache Jena - JDBC TDB Driver ............[5:52.688s]
Apache Jena - JDBC Driver Bundle .........[13.157s]
The build (mvn clean install in jena-jdbc having rebuild jena) is messy;
It's not finding a log4j setup which might be related to the output that
is Exceptions printed e.g.
22:35:01 ERROR JenaStatement :: Invalid SPARQL update
com.hp.hpl.jena.query.QueryParseException: Encountered " "select"
"SELECT "" at line 1, column 1.
and a long trace.
There are enough of these that my terminal buffer lost the top of the
output so I don't know how many there were.
and many like:
5602 [main] ERROR org.apache.jena.jdbc.JenaDriver - Invalid value for
post-processor parameter, references a class that did not exist
java.lang.ClassNotFoundException: NoSuchClass
5601 [main] ERROR org.apache.jena.jdbc.JenaDriver - Invalid value for
pre-processor parameter, references a class that exists but does not
have an appropriate constructor
java.lang.InstantiationException: com.hp.hpl.jena.graph.Node

Yeah we use JDK6 exclusively here at YarcData
The fix is either to make the change or I think we can use the compiler
plugin to restrict these modules to JDK 6 for the time being?

org.apache.jena.jdbc.metadata.results.MetaResultSet is not abstract and
does not override abstract method
<T>getObject(java.lang.String,java.lang.Class<T>) in java.sql.ResultSet
and then some others.
Maybe it's this:

jectstring-classt-in-jdk7
I'm using a Java7 compiler in Java6 mode so it's the JDK7 runtime.
If so, the fix is to add, without @Override but with suppressed warnings:
<T> T getObject(int columnIndex, Class<T> type) throws SQLException
<T> T getObject(String columnLabel, Class<T> type) throws SQLException
