Rollback error while reader encounters an error

[hailspring]

I am getting an error while the reader encounters an error while reading and the writer could not roll-back, as it does not have the marker:

**** is the package name.

It also as a result does not update the database record with the job status, so when I try to rerun it, it says the job is already running.

I am using 1.0.1 version

This is a known issue:

http://jira.springframework.org/browse/BATCH-548

Although, it should still store the meta-data.

The fix is to either buffer items so that reset won't be called on the LineReader, or to clean the data so that you're not skipping so much in between commits. (The fix I'll probably put in will be to buffer the items)

[hailspring]

Thanks Lucas! will the fix available in 1.1.0? Do we have any estimate on when it will be released(just curious)? (Jira page says 30th May).

thanks guys!

Technically it hasn't been addressed yet, but we should be tackling it before 1.1 goes out.
