I noticed that the function
delete( String lfn, ReplicaCatalogEntry tuple ) is broken for JDBCRC.

To test it ,

in RCClient.java line 564, change the boolean parameter to true from false
result = m_rc.delete(entries, false);

I used these mappings
corbusier:jdbcrc vahi$ cat rc.in
f.a gsiftp://sukhna.isi.edu/tmp/f.a pool="sukhna" karan="vahi"
f.b gsiftp://corbusier.isi.edu/tmp/f.b pool="local"
f.c gsiftp://corbusier.isi.edu/tmp/f.c pool="local"

Notice it has additional attribute key value pair

in my database
sqlite> select * from rc_lfn;
27|f.a|gsiftp://sukhna.isi.edu/tmp/f.a|sukhna
29|f.b|gsiftp://corbusier.isi.edu/tmp/f.b|local
28|f.c|gsiftp://corbusier.isi.edu/tmp/f.c|local

sqlite> select * from rc_attr;
27|karan|vahi

however, now when i run pegasus-rc-client --delete option against same mappings file, the database still have the mapping in rc_attrib table
sqlite> select * from rc_lfn;
sqlite> select * from rc_attr;
