Upgrade to 0.7.0 renders some data unreadable

[Jmennius]

After the upgrade of ascicolor to 0.7.0 from 0.6.2 Jenkins complains that some data is unreadable.

Test environment

• Jenkins Version: 2.205
• AnsiColor Version: 0.7.0 (upgraded from 0.6.2)
• Hostsystem: Ubuntu 18.04

Expected behavior

Nothing unusual after the upgrade.

Actual behavior

Jenkins greets with You have data stored in an older format and/or unreadable data.
and the table lists entries with:
CannotResolveClassException: hudson.plugins.ansicolor.ColorizedAction

Steps to reproduce the behavior

Have some jobs run with pre-0.7.0 ansicolor, upgrade to ansicolor 0.7.0 - observe Jenkins complain about "old data".

Apparently this is caused by 96aa4e0 which moved ColorizedAction into another package.

This affects me as well.

This is harmless. ColorizedAction now serves a much broader purpose.
You can safely Discard Unreadable Data (on the Manage Old Data page) or Dismiss it altogether.

How can I fix the problem permanently?

Too many "Unreadable Data points" have impact on jenkins performance, so having this in degrades jenkins across time.

Anyone has any pointers on how to avoid this altogether ?

we're running ~100 jenkinse. Clicking Discard Unreadable Data on all of the servers is really painful. Especially if you have to check that there are no other, probably more important warnings in between. I'd love to have a more viable solution. Also considering the performance degradation aspect.

This continues to be an issue. The solution proposed is not acceptable. which was: "This is harmless. ColorizedAction now serves a much broader purpose.”

Let's reopen this. Please contribute a fix.
