Problem

When navigating to the Board Active Sprints section, you receive an 'Internal Server Error' in the top of the page.

The following appears in the Jira logs:

1 2 3 4 5 6 7 Caused by: java.lang.ArrayIndexOutOfBoundsException: 4000 at org.codehaus.jackson.impl.Utf8Generator.writeString(Utf8Generator.java:565) at org.codehaus.jackson.map.ser.std.StringSerializer.serialize(StringSerializer.java:28) at org.codehaus.jackson.map.ser.std.StringSerializer.serialize(StringSerializer.java:18) at org.codehaus.jackson.map.ser.BeanPropertyWriter.serializeAsField(BeanPropertyWriter.java:446) at org.codehaus.jackson.map.ser.std.BeanSerializerBase.serializeFields(BeanSerializerBase.java:150) ... 217 more

Cause

The error is caused because Jira is not able to correctly parse an emoticon in the title of an issue included in the project's agile filter.

Resolution

Look through the issues included in the filter for that project and remove any emoticons in the title. No re-indexing should be needed and the results are immediate.
