Problem to serve station data in gds

Dear Edigley Fraga,
I don't really have a good answer for this one. The GDS java files
were compiled with java 1.5, and I cannot reproduce your error on
that system. However, I am running GDS 2.0 on another system running
java 1.6, and I do see that error message in my log files. The
strange thing is that I cannot reproduce the java error reliably, and
the .info request seems to be fulfilled successfully in spite of the
java error. If I weren't looking in the log files, I'd never know
there was a problem! For the cases when the java errors appear, a
browser 'reload' of the .info request works fine without the error
messages. You can try recompiling the GDS on your system with the
$GDSHOME/src/makejar. This gave me a lot of warnings, but the
recompile was successful. After recompiling, I am unable to get any
java errors for .info requests on station data sets.
