This worked with Lucee release 5.2.6.24:

<cfstoredproc procedure="contens_reset_sequence" datasource="contens5_unittests_oracle">
<cfprocparam cfsqltype="cf_sql_varchar" type="in" variable="seqname" value="seq_co_logsessions">
<cfprocparam cfsqltype="cf_sql_varchar" type="in" variable="tblname" value="co_logsessions">
<cfprocparam cfsqltype="cf_sql_varchar" type="in" variable="tblfield" value="logsession_ID">
</cfstoredproc>

But not with later releases, see attached image
