When running an execution definition from within SilkCentral Test Manager you may receive a "java.io.UTFDataFormatException" error message as shown below:
If you receive this error check the Frontendserver.log file which is located at the following location:
"C:\Documents and Settings\All Users\Application Data\SilkCentral\log"
In this log file you should see entries similar to the following:
I;OV;2010-11-23;09:52:44;TM;http-80-123;Could not create package for MTC. execDefRun id: 3859445 E;OV;2010-11-23;09:52:44;TM;http-80-123;java.io.UTFDataFormatException
The reason for this error is that when an execution with manual test definitions is started, a package for the manual testing client is created. This package creation fails if the description of an issue in an external tracking tool exceeds 65KB. Examples of external issue tracking tools are JIRA and Bugzilla.
To workaround this issue you should shorten the issue descriptions in your issue tracking tool and attach the full versions to the issues in text files instead.
