Chip Hartney commented on DERBY-3091:
-------------------------------------
Here's a simple IJ session that reproduces the problem in my env (only when
query logging is turned on) with the data file in my prior attachment...
ij version 10.2
ij> connect 'jdbc:derby:OrderEntryDB;user=xxx;password=xxx';
ij> CREATE TABLE TEMP.ZJVTERMS ("CODE" INTEGER NOT NULL, "TEXT" CHAR(16) NOT
NULL);
0 rows inserted/updated/deleted
ij> CALL SYSCS_UTIL.SYSCS_IMPORT_TABLE ('TEMP', 'ZJVTERMS',
'C:\DOCUME~1\Chip\LOCALS~1\Temp\20070724-124300-ZJVTERMS.dat',';','~',null, 1);
ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
Note that it does not matter what table structure or what data I use. (More
accurately, I have yet to find a table structure or data file that avoid this
problem.)
Be aware that, as opposed to specifying the logging as an argument to the
command, I am specifying the logging properties through a derby.properties file
with the following content:
derby.infolog.append=false
derby.language.logStatementText=false
derby.language.logQueryPlan=true
As noted before, the query plan does appear to be generated. At least part of
it is.
The log output, including stack trace, is:
