failure to return read method from PropertyDescriptor getReadMethod()

using jdk 1.4.2_06-b03 or jdk 1.4.2_07-b05 put the ctalog-ejb-client.jar from petstore distribution (either 1.3.1 or 1.3.2) in the classpath. Compile and run TestJDK.java below. On either verions the getAttribute() method will not be shown in the output. With jdk 1.4.2_04-b05 it will.
