Type conversion should only happen for correct values

[Stefan Glase]

Type conversion should only happen for compatible values and not be enforced for all values.

See:

jira-scrum-poker/src/main/java/de/codescape/jira/plugins/scrumpoker/service/EstimateFieldServiceImpl.java

Line 68 in f509808

 issue.setCustomFieldValue(estimateField, Double.valueOf(estimate)); 

A String with the value „S“ would be converted into Double for a custom field that only accepts Numeric values of type Double.
