Re: Is the checkpoint rebuilder still meant to work from main()?

Hi Hari,
Here's the logs. Also adding the patch afterwards. Don't think the mailinglist accepts attachments so just going to paste it in after the logs(note that I changed the parameter for the checkpoint dir so it didn't overlap with conf)

Hi Juhani,

Could you please send the full logs? I don't remember if the main method was 
updated with the new file channel format and also with the encryption patch. 
The CheckpointRebuilder works fine if you call from the channel starup (using 
the use-fast-replay parameter).


Thanks,
Hari
