Thanks for the information. I didn’t notice any problems with the Java installation at all after upgrading to Mavericks, but I have seen the activation issue on one computer here (but not on another). I’m not exactly sure what’s happening, but it looks like the FLEXlm licensing component is looking for a different hostid after the upgrade. Typically the MAC address of the Ethernet card labeled “en0” is the one used for licensing and is the one encoded in the license.dat file. However, after updating to Mavericks it appears FLEXlm is using the card labeled “en1” to authenticate on one of our machines (which is not the MAC address in the license.dat file). I don’t know what would be causing this change in behaviour, but In any case re-activating Maple has solved the problem.
