Old scheduled issues not displaying after upgrade

[Dmitriy Koff]

After JIRA upgrade (7.1.x to 7.12.3) and plugin upgrade (5.x to 5.3.2) old scheduled issues (created before upgrade) not displaying, and not available for edit.

1) Manage Scheduled Issues (/secure/ManageScheduledIssues!default.jspa) stuck in endless loop, trying to display issue list

2) If I try to open old Scheduled Issue directly by ID (like /projects/ITDPT?selectedItem=pl.com.tt.jira.plugin.theschedulerpro:scheduled-issues-project-tab-panel-link&scheduledJobId=7) , I get "Unexpected exception".

3) If I create new scheduled issue, and access it directly -- it works.

Upd: Removing and reinstalling the plugin did not solve the problem.
