Error occured when translating description longer than 255 characters

When trying to translate a resolution by adding more than 255 character under the description field, the following error message occurs:

com.opensymphony.module.propertyset.IllegalPropertyException: String exceeds 255 characters.
at com.opensymphony.module.propertyset.AbstractPropertySet.setString(AbstractPropertySet.java:365)
at com.atlassian.jira.propertyset.JiraCachingPropertySet.setString(JiraCachingPropertySet.java:318

BY right, JIRA should have validate the limit of inserted characters if it is intended to be 255 character .

Steps to reproduce are:

• Go to Administration->Issue Settings->Resolutions
• Click on Translate resolution on top of the page
• Translate one of the resolution by inserting more that 255 character in the Description field
• Then press Update
