I commited the IOUtil class contributed by Martin to the OpenJUMP SVN. The class can be found in the org.openjump.core.apitools package. I changed the name of the class from IOUtil to IOTools to match the other class names in the package.
Please let me know if there are any questions or problems. Thanks again for the contribution Martin.
