I have a render transform process that is very similar to the heatmap
example.
-Geoserver 2.4.4
-Tried under both tomcat and jetty (war distribution, and using the
embedded jetty distro)
-WPS extension is installed in both
-Demo -> WPS Builder -> my function (loc:Decimation) appears and properly
shows the parameters
-Java 7 (Oracle, 45 and 51)
I modified the heatmap example SLD (just noticed I forgot to change the
description) -

I take a layer (that works with the standard point style), and apply that
style. One of three things happens when the Publish tab tried to generate
the getLegendGraphic.
1) - It works and I see the point style

2) Null Pointer exception -

3) Unable to find function aaa:Decimation -

Request: getServiceInfo
02 Feb 10:02:27 ERROR [geoserver.ows] -

If one of these was consistent, it would make more sense, but I can cycle
through all three by just stopping, starting, logging in, clicking on
layer, then publish (if the style referencing aaa:decimation is present)
I see this same behaviour with tomcat and jetty. I have tried increasing
the permgen, new, and heap size on all three (and also left them as
default) with the same behaviour
export JAVA_OPTS="-XX:MaxPermSize=513m -XX:MaxNewSize=513m -Xmx7g"
was what I had for the latest run, and I verified it was taking effect via
ps aux | grep java
Here's a log of startups/shutdowns:
9:57AM
startup - Null Pointer Error
shutdown
startup - Null Pointer Error
shutdown
startup - Works
shutdown
startup - Works
shutdown
startup - Works
shutdown
startup - Works
shutdown
startup - Unable to Find Function
shutdown
startup - Null Pointer Error
shutdown
startup - Works
10:10AM
Note, that in every case, under Demo -> WPS Request Builder I was able to
see my process and interrogate the parameters correctly (even under the
Unable to Find Function instance)
I don't think I had this same issue in 2.3x - but I need to re-download it
and verify - so that might be just selective memory. That said, I don't
want to be pegged to an old version.
Any thought, suggestions, or directions are appreciated
