Error when trying to get netcdf

[jkburges]

An exception occurs when trying to generate a NetCDF under certain conditions.

Steps to reproduce
From the command line:

1. cd src/extension/ncdfgenerator
2. mvn exec:java -Dexec.mainClass=au.org.emii.ncdfgenerator.Main -Dexec.args="-d jdbc:postgresql://dbprod.emii.org.au:5432/harvest?loginTimeout=1000&ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory -u HERE_BE_USER -p HERE_BE_PASSWORD -P anmn_ts -s anmn_ts"

Note that the same thing happens from the context of the WPS process, which can be triggered equivalently from the portal.

What happens
After a minute or two:

Write exception java.lang.IllegalArgumentException: dimension length must be > 0 :0 at ucar.nc2.NetcdfFileWriteable.addDimension(NetcdfFileWriteable.java:247) at au.org.emii.ncdfgenerator.DimensionImpl.define(DimensionImpl.java:26) at au.org.emii.ncdfgenerator.NcdfEncoder.writeNext(NcdfEncoder.java:188) at au.org.emii.ncdfgenerator.Main.main(Main.java:110) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.codehaus.mojo.exec.ExecJavaMojo$1.run(ExecJavaMojo.java:293) at java.lang.Thread.run(Thread.java:745)

What should happen
A valid zip of NetCDF files is produced.
