Create index statement does nothing

I'm executing a create index statement in jdbc. The statement executes without error but the index does not show up in the database. I execute "select * from pg_indexes where tablename = 'mkteodprice'" in pgAdmin and it returns no rows.
When I execute "create index "Temp_4419_1507660884753" on systestdata01p.mktEODPrice ( priceDate, tradingItemId, PacVerToFeedPop )" in pgAdmin the index is created as expected.
The java statement that I'm using is "int n = _statement.executeUpdate( sql );" Later in the java code I attempt to drop the index and it fails because the index does not exist.

JDBC driver build number: 42.1.4
Server version: 9.6
Java Version: 1.8.0_144
pgAdmin version: 2.0
