James Thomas commented on CONNECTORS-1524:
------------------------------------------
I have found another issue that manifests across Java versions.
If I start MCF 2.11 and Documentum processes using Java 9 or later I find that
attempting to view or edit a Documentum connector will result in this error
into the console:
{noformat}
3 [RMI TCP Connection(2)-127.0.0.1] ERROR
com.documentum.fc.common.DfPreferences - [DFC_PREFERENCE_BAD_VALUE] Bad value
for preference "dfc.date_format", value="M/d/yyyy, h:mm:ss a"
com.documentum.fc.common.DfException: Illegal syntax found in the date format
'M/d/yyyy, h:mm:ss a'. The default localized short date format will be used.
{noformat}
I can work around this by adding this line to my dfc.properties:
{noformat}
dfc.date_format=yyyy.MM.dd HH:mm:s{noformat}
I don't see this issue with Java(TM) SE Runtime Environment (build
1.8.0_181-b13)
