title: What is use of validation.properties for ESAPI.encoder().encodeForSQL in ESAPI
body: <p>I am using ESPAI for SQLInjection prevention in Java.
  I am only using <code>ESAPI.encoder().encodeForSQL(ORACLE_CODEC,queryparam))</code> method. </p>
  
  <p>If I do not include <code>validation.properties</code> in the <code>esapi.properties</code> I get <code>IllegaleStateException</code>. </p>
  
  <p>Please let me know why encodeForSQL() will require validation.properties.</p>
