Summary

0001699: NPE in com.caucho.quercus.lib.db.OracleModule.oci_error(OracleModule.java:706)

Description

I've downloaded 'OracleEditor.php' from sourceforge.net, a single php file that should connect to an Oracle Database.

The file OracleEditor.php could be successfully displayed on the screen offering to enter username, password and (tnsnames.ora) service name.

After the 'Connect to Oracle' Button, a NullPointerException is thrown:

At least on this very verbose logging level, I can see the real Error:

FINE com.caucho.quercus.lib.db.Oracle java.sql.SQLException: E/A-Exception: The Network Adapter could not establish the connection

However, in my hunmble opinion the method oci_error() in OracleModule.java should check if 'conn' is != null.
