When I try to query on an "any" association with Hibernate 3.2/PostgresQL 8.0.3 (i.e. find all objects with a certain object in one of its fields, and that field is a java interface), I get an error from inside postgres complaining that too many columns are being bound. It is very easy to reproduce with just a little code, all of which is included below. Can anyone help me get past this? I have to use an any here; I have many classes that implement many different interfaces and this is the only way to map the associations.

I use jprofiler to profile the back end of my application and it works great, but when I try to set resin to use -Xrunprofiler (even with the offline parameter), it will not start up-- it hangs instantly and doesn't log anything at all, even with -verbose on. I notice that even forgetting jprofiler and just using the primitive -Xrunhprof:cpu=samples,heap=sites causes resin to hang in the same way. Does anyone out there use jprofiler with resin successfully? Or even the dumb runhprof thing?
