Description Martin Oberhuber

2011-09-16 09:07:31 EDT

Build ID: dltk-core-sdk-S-3.0.1-201108261011 / PDT 3.0 N201107150957

I see the following error printed to stdout when creating / importing some code initially into an empty workspace / config ... printing to stdout is generally discouraged as bad practice, and doesn't give a good impression to customers / end users.

I'd like to understand what this means and how it can be fixed or worked around. Is it a known defect in org.h2 ? Or is it probably mis-configured? Or is it a JVM bug (I use Sun/Oracle 1.6.0_21):
