[Milan Chheda [INFOSYSTA]]

I am getting this error too. We are using JIRA 8.1.0 with SQL Server 2016. 

Any resolution or work-around here?

[Marcos PS [DEISER]]

Hello Luu,

There are some issues similar to yours but no serious workaround neither hotfix was offered, not at least as far as I saw in a quick search. You should report this issue to Atlassian support, follow this link and fulfill the forms.

Best regards,

Marcos.

PS: This is something like using a sledgehammer to crack nuts, but in order to discard a plugin cache corruption, you can shutdown Jira, then delete these folders:

<JIRA_HOME>/plugins/.bundled-plugins

<JIRA_HOME>/plugins/.osgi-plugins

And start Jira again.

Hi Marcos,

After following your instructions in the P/s section. The bug's still there and those folders automatically created again.
I found an old accept reply (here) . Is this one which you mentioned ??

Thanks and best regards.
