Hi As there wasn't any voices against the change, I am now going announce that mkgmap will now require java 1.6. Just in time really as there is just over a month before 1.5 is end-of-life'd by Sun ;) During a transitional period I will compile it with target 1.5 and detect if 1.6 is not being used print a hopefully useful error messages instead of a cryptic stack trace. After a while I plan to drop that code and just compile for 1.6. If you see anything on the wiki or elsewhere that refers to java 1.5 feel free to change it. ..Steve
