com.sun.jdi.InvocationException occurred invoking method in "new Configuration().configure().buildSessionFactory()"

I am seeing NullPointerException when I try to buildSessionFactory. However, on clicking the exception object in Eclipse's debug mode, the message I see is com.sun.jdi.InvocationException occurred invoking method.

I am seeing this behavior only after having introduced a new Entity class. The table to which the class is bound, exists. There are no typos. hibernate.cfg.xml is parsed successfully too. A fatal exception is thrown after hibernate tries to bind the new class to the table.

  1. hibernate.cfg.xml
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
    <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
    <property name="hibernate.connection.url">jdbc:oracle:thin:@lvsspldb06.qa.xxxx.com:1556:ICMDBTST</property>
    <property name="hibernate.connection.username">ICMAPP</property>
    <property name="hibernate.connection.password">ICMAPP</property>
    <property name="show_sql">true</property>
    <mapping class="com.xxxx.top.entity.Release"></mapping>
    <mapping class="com.xxxx.top.entity.Package"></mapping>
    <mapping class="com.xxxx.top.entity.Top"></mapping>
    <mapping class="com.xxxx.top.entity.PortAssignment"></mapping>
  </session-factory>
</hibernate-configuration>

  1. desc package_portassignment; gives an output. So that confirms that the table exists.

  2. Console log

  1. The newly added Entity class

PortAssignment.java. Was not able to post it inside this question as stackoverflow was giving me much grief with the formatting.

I rewrote the new class and the error disappeared. I admit, I am embarrassed but I think there was a typo in the annotation Column(name=...) for one the properties.

I suppose this caused a NullPointerException in one of the internal classes of Hibernate (specifically org.hibernate.annotations.common.reflection.XClass.getDeclaredProperties).

Thanks Channa Jayamuni for your thoughts.
