ResultSet.findColumn() is not compliant with API.

The API states that findColumn() throws SQLException if the column is not found. However, a SQLGrammarException is thrown, breaking the API.

Simple test:
try { String testQuery = "SELECT 0"; PreparedStatement testStmt = connection.prepareStatement(testQuery); ResultSet rs1 = testStmt.executeQuery(); rs1.findColumn("dummycolname"); } catch (SQLGrammarException e) { throw new IllegalStateException("Wrong Exception", e); } catch (SQLException e) { // Correct exception }
