Description

When using the runtimeinfo command with the org.apache.derby.drda.NetworkServerControl program
It seems that the output is truncated, as if the output exceeeds some threshold or met some internal timeout, so that it does not wait for the rest of the data.

In that case, the output starts with

-- Derby Network Server Runtime Information ---

---------- Session Information ---------------
Session # :1
Database :harvestDatabase/fullhddb
User :APP
# Statements:12

but does not end with something like

-------------------------------------------------------------
# Connection Threads : 3
# Active Sessions : 3
# Waiting  Sessions : 0
