Issue

After upgrading to Security Analytics 10.5.0.1, the error message below is seen on Threat metadata during investigations.
 

Failed to convert from type com.rsa.smc.sa.investigation.navigate.common.domain.model.MessageDataWrapper to type com.rsa.smc.sa.investigation.navigate.values.domain.model.MetaValueLoad for value 'com.rsa.smc.sa.investigation.navigate.common.domain.model.MessageDataWrapper@551777aa'; nested exception is java.lang.ArithmeticExceptionClick to Reload

Image description

Cause

In values calling any meta whose "group" is NOT ZERO, we get the Meta Count as ZERO. For such meta values we show a value such as  "(10000 - 33%)" for the meta value count. 
This causes the Security Analytics server to throw an Arithmetic Exception while calculating the Percentage values for that Meta.

Resolution

This issue is permanently resolved in Security Analytics 10.5.1, in which changes have been made in the Security Analytics server to Display "Error - <Number>" as the Session Count when a Non-Positive number is received as the Session Count.
