Bundling in jackson causes problems. #2

Bundling in jackson causes problems.

My app includes jackson-core-asl-1.5.5.jar. This appears to be incompatible 
with the jackson classes that you sneaked into bqjdbc-0.0.7.jar. I confirmed 
this was the issue by removing my copy. After that I was able to connect. But 
this breaks other things in my app.

I realize you don't want to separate your driver into 2 jar files. And while 
that would make the problem more apparent... it wouldn't really solve it 
anyway. I'm not sure what the ideal solution is. Maybe building your classes 
with an alternative package would be a possibility.

This is a non-complete list of some clashing classes:
$ jar -tf 
../ireport/4.6.0/modules/ext/org.codehaus.jackson/jackson-core-asl-1.5.5.jar | 
grep JsonGenerator
org/codehaus/jackson/JsonGenerator$Feature.class
org/codehaus/jackson/JsonGenerator.class
org/codehaus/jackson/impl/JsonGeneratorBase$1.class
org/codehaus/jackson/impl/JsonGeneratorBase.class
org/codehaus/jackson/util/JsonGeneratorDelegate.class

$ jar -tf ~/JDBC/bqjdbc-0.0.7.jar | grep JsonGenerator
com/google/api/client/json/JsonGenerator.class
org/codehaus/jackson/JsonGenerator$Feature.class
org/codehaus/jackson/JsonGenerator.class
org/codehaus/jackson/impl/JsonGeneratorBase$1.class
org/codehaus/jackson/impl/JsonGeneratorBase.class
org/codehaus/jackson/util/JsonGeneratorDelegate.class

That's true, the supplied jar package contains all the dependencies required to 
run 3rd party tools. I will ask the guys to upload the standalone package as 
well up this big bundle. 

So, the solution will be: 

 - have this big bundled jar file with a warning message
 - have a driver only jar without the dependencies plus a Wiki page where everyone can find the list of the required 3rd party packages

Now we have two jars to download:

bqjdbc-0.0.8-standalone.jar - this one is for you, without dependencies
bqjdbc-0.0.8.jar - this one is with dependencies for instant usage

All required jar files to run the standalone one are listed here:
