Spent about 3 hours trying to install the latest java ee sdk on my natty narwhal with no luck. It usually hang with 45% and 5seconds left forever. Might be I’m a bad googler but turned out that there is a bug in the installer which prevents the installation from continuing. The workaround is to disable the network connections before the installation begins(disabling while it is hanging did not work for me). You won’t have the Update
Tool Bootstrap tool configured but still you’ll have the sdk installed and ready for your tests/work.
