Ok Justin, I will fix the bug, continue investigation and send you a report.

If you look at the code that processes the bounds query it processes each envelope returned by the dialect and checks for an instanceof ReferencedEnvelope and merges it in taking the crs into account. There might be a bug there but at least supporting difference crs's is intended.

[Geotools-devel] Confusion looking at the code in JDBCDataStore
1) The method buildEnvelopeAggregates causes some confusion for me. I have a sql table with 3 Point attributes, each with a different SRSid. The method iterates over all geometry attributes for extent calculation, but the sql attribute name passed to the dialect is always the attribute of the default geometry. I assume this is a bug ? 2) Even if 1) would work in the correct manner, all the extents are merged resulting in one single extent (method getBounds). This is correct if all geometry attributes have the same SRSid, but it is nonsense if these attributes do not have the same SRSid. Does this mean that geometry attributes with different SRSids are not supported ?
