Hi,
after updating GeoServer from 2.10.1 to 2.12-RC1 I'm experiencing the same
behaviour when POSTing to the REST API for seeding tiles in the integrated GWC.
Sending the xml document
<?xml version="1.0" encoding="UTF-8"?>
<seedRequest>
<name>workspace:layer</name>
<bounds>
<coords>
<double>1445211.16687</double>
<double>6064302.74797</double>
<double>1461859.20951</double>
<double>6083740.16150</double>
</coords>
</bounds>
<gridSetId>EPSG:3857hidpi</gridSetId>
<zoomStart>17</zoomStart>
<zoomStop>17</zoomStop>
<format>image/png8</format>
<type>reseed</type>
<threadCount>4</threadCount>
</seedRequest>
to /geoserver/gwc/rest/seed/workspace:layer.xml results in an HTTP 500
response. Geoserver.log is showing the following exception:
2017-10-19 15:16:05,914 ERROR [geoserver.rest] - seedRequest
com.thoughtworks.xstream.mapper.CannotResolveClassException: seedRequest
at
com.thoughtworks.xstream.mapper.DefaultMapper.realClass(DefaultMapper.java:81)
...
A similar problem has been discussed on StackOverflow
(https://stackoverflow.com/questions/10438124/xstream-cannotresolveclassexception),
which leads me to the conclusion, that xstream fails to deserialize the posted
xml document because the specified type, in my case 'seedRequest', in your case
'user', has not been found in the current java package. As I'm not a java
developer I'm unable to dig in further.

Daniel Calliess
