Hello,

yesterday our jira worked perfectly with the mylyn connector.
Today we needed 3 hours to find out that our jira version (Standard Edition, Version: 3.13.3-#344)
returns a wsdl that contains a RemoteServerInfo element with an serverTime subelement.

The symptom:
If I try to validate the connection in the mylyn connector dialog I get the error message "Invalid element in org.eclipse.mylyn.internal.jira.core.wsdl.beans.RemoteServerInfo -serverTime"
This Bug is reported at http://dev.eclipse.org/mhonarc/newsLists/news.eclipse.tools.mylyn/msg01772.html.
The jira mylyn connector bugfix is included in the http://download.eclipse.org/tools/mylyn/update/extras/plugins/org.eclipse.mylyn.jira.core_3.1.1.v20090411-0400-e3x.jar plugin.

It seems that jira automatically retrieves the wsdl (and therefore updates to the wsdl) from somewhere because everything worked fine before yesterday.
We worked about one month with our mylyn jira connector and that jira version. We never made a update (neither mylyn nor jira). So where does this change come from??

Our solution:
We downloaded http://download.eclipse.org/tools/mylyn/update/extras/plugins/org.eclipse.mylyn.jira.core_3.1.1.v20090411-0400-e3x.jar.
Renamed it with the name of the current plugin in our installation and then replaced the current installation's plugin.
We are lucky that it is binary compatible

I know a bad workaround, but software development seems to be working around instead of targeting the real goals.
