Oracle JDBC connection exception in Solaris but not Windows?

I have some Java code that connects to an Oracle database using DriverManager.getConnection(). It works just fine on my Windows XP machine. However, when running the same code on a Solaris machine, I get the following exception. Both machines can reach the database machine on the network. I have included the Oracle trace logs.

The above exception is also thrown if I use OracleDataSource instead of the generic DriverManager.getConnection().

Any ideas on why the behavior is different in the different environments?

It looks like there's an error in TNSNAMES.ORA from the lines

java.lang.ArrayIndexOutOfBoundsException: 31
        at oracle.net.nl.NVTokens.parseTokens(Unknown Source)
        ...
        at oracle.net.resolver.TNSNamesNamingAdapter.loadFile(Unknown Source)

I'm not up on the oracle configuration from solaris, but assuming it's similar to the win version, maybe you have an issue with the formatting of this file. Can you connect through a sqlplus console from that box?

One thing I forgot to mention is that my application is built for Java6. The Oracle database is 10g, but for whatever reason, upgrading to the 11g version of the driver (i.e. ojdbc6_g.jar) fixed the problem.
