Problem Note 60202: Decision Tree issues a java.lang.RuntimeException error

DetailsHotfixAboutRate It

If you create a decision tree that includes a node containing more than 1,500,000 observations and pruning is turned on, an error similar to the following might be issued:

(mx.rpc::Fault)#0
  content = (null)
  errorID = 0
  faultCode = "Server.Processing"
  faultDetail = (null)
  faultString = "java.lang.RuntimeException : com.sas.lasr.LASRException:
java.io.EOFException"
  message = "faultCode:Server.Processing faultString:'java.lang.RuntimeException
: com.sas.lasr.LASRException: java.io.EOFException' faultDetail:'null'"
  name = "Error"
  rootCause = (Object)#1

        suppressed = (Array)#4
      errorCode = 0
      localizedMessage = "java.io.EOFException"
      logTableName = (null)
      message = "java.io.EOFException"
      severity = 0
      suppressed = (Array)#4
    localizedMessage = "com.sas.lasr.LASRException: java.io.EOFException"
    message = "com.sas.lasr.LASRException: java.io.EOFException"
    suppressed = (Array)#4
null

This problem can occur when either SAS® Visual Statistics or the IMSTAT Procedure in SAS® In-Memory Statistics is used to create the decision tree.

To circumvent this problem, turn off pruning.
