Unable to load native library: java.lang.NullPointerException under Mac OS X

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Follow the instructions verbatim to build and run the *.jar file

What is the expected output? What do you see instead?

Building the *.jars went fine.

The very first that appears on the screen when calling mdb-sqlite.jar is:

macbook:mdb-sqlite-1.0.2 username$ java -jar dist/mdb-sqlite.jar
database.mdb database.sqlite
JarClassLoader: Warning: Unable to load native library:
java.lang.NullPointerException

What version of the product are you using? On what operating system?

Version 1.0.2 on Mac OS X 10.6.2 running Java(TM) SE Runtime Environment
(build 1.6.0_17-b04-248-10M3025)

Please provide any additional information below.

Had the same problem on win7 64bit
replaced the sqlitejdbc-v048-nested.jar in the lib directory with the latest 
from here http://www.xerial.org/trac/Xerial/wiki/SQLiteJDBC
then ant clean, ant dist, plus the patch - line 256 add:
                    case FLOAT:
                        prep.setFloat(i + 1, ( (Float) row.get(column.getName())));
                        break;
                    case DOUBLE:
                        prep.setDouble(i + 1, ( (Double) row.get(column.getName())));

after 
switch (column.getType()) {

The fix purposed by martinsi...@gmail.com works beautifully!

I have a ~ 1GB File, the conversion had no warnings! How confident should I be 
about the conversion? 100%? I'm running SQL commands on both trying to compare 
the DBs and assert this, but it's hard to tell and I'm unable to tell compare 
everything on a DB of this size.

Thanks. That seemed to work. Just a note from the #10 comment. You should put 
an extra   break;
after the prep.setDouble...

I've applied the suggested patch on win7-x64 (obviously including the missing 
break) and replaced sqlitejdbc-v048-nested.jar with sqlite-jdbc-3.8.7.jar from 
Xerial
Works great - thanks!
