Symptoms

In WebLogic Server 10.3.2 and 10.3.3, when trying to use a foreign JNDI provider for an application, and if you need to set a JNDI lookup timeout to the foreign server (which does not have to be available at all times), when you try to set the timeout for example to 10000ms as follows:

<jndi-property>
  <key>weblogic.jndi.requestTimeout</key>
  <value>10000</value>
</jndi-property>

You will get a ClassCastException in weblogic.jndi.Environment when it tries to cast the String value from above to a long, for example:

Caused By: javax.naming.ConfigurationException: Call to NamingManager.getObjectInstance() failed: [Root exception is java.lang.ClassCastException: java.lang.String]; remaining name ''

If you try to use <value>"10000"</value> instead of <value>10000</value>, you will got the following error:
