Hi mcobby,

Could you please clarify what you mean by

will we be able to upgrade renderer on it's own or be forced into a full upgrade to 6.3?

Thanks in advance.

We get this bug in only one workflow and are in progress of upgrading to 6.2.7
Question: When 6.3 is released, will we be able to upgrade renderer on it's own or be forced into a full upgrade to 6.3?

This error appears due to the bug inside the 3rd party library that is used in JIRA 6.2 to render workflow diagrams. The workaround is to run JIRA 6.2 using Java 6. Or to use Text Mode for workflow viewing/editing.

All usages of that library were removed in JIRA 6.3 currently scheduled to be released by the end of June. So 6.3 is not affected by this bug.

Due to the fact that: a) 6.3 will be available soon, b) there is a workaround, c) problem doesn't appear to be very common, I suggest we close this as "Won't fix".

The bad news is that we discovered 2 more bugs while trying to import the workflow XML attached to this issue: ~~JRA-38398~~ and ~~JRA-38399~~. Both of them will be fixed in 6.2.7
