Re: Latest Java release causes runtime exception

[Dennis Reedy]

This also happens with updates to Java 1.6 (u39). The fix looks to be simple. 
The Levels class seems to be the issue. Unless I'm missing something, it seems 
straight forward enough the create a custom level without using the 
ClassReplacingObjectOutputStream and the LevelData approach. I modified Levels 
(attached on my reply), rebuilt and everything seems to load successfully. 
Without this fix I have a complete show stopper for some of my installations.

I'd like to request that this gets fixed ASAP and a new release produced.

Thanks

Dennis
