title: java security exception: sealing violation while trying to connect to database
body: <p>I am facing an issue with oracle db connection after changing java runtime to 1.6.
  Earlier our application used 1.5 java runtime and now we are migrating 1.6. Application is throwing the following exception while trying to connect to oracle 10g db:</p>
  
  <blockquote>
    <p>failed. Error: Verify operation
    failed. Errors: [ORACLE-10002: Error
    received from connection to Oracle
    database +ASM:
    java.lang.SecurityException: sealing
    violation: package oracle.jdbc is
    sealed]</p>
  </blockquote>
  
  <p>It is working properly if I use jre 1.5 instead of 1.6 jre.
  It is working fine with oracle 11g database and jre 1.6 combination.
  Have any of you faced similar issues? Thanks for your time.</p>
