While editing org.netbeans.lib.ddl.adaptors.DefaultAdaptor from the db module so
that I could compile NetBeans using JDK 6, I was copying some methods from
java.sql.DatabaseMetaData into it.  When I pasted
	ResultSet getClientInfoProperties()
		throws SQLException;

The exception below was thrown (note that currently my project metadata for the
db project is corrupt because of project metadata incompatibilities between
build 060803 which I'm using and the trunk versions of the standard modules -
it's why I'm trying to build the trunk [since the trunk build I downloaded is
hopelessly broken but maybe I can fix my local one]).
