The attached program uses Introspector.getBeanInfo() to get the BeanInfo associated with the class specified on the command line, and then enumerates the PropertyDescriptor[] returned by BeanInfo.getPropertyDescriptors().

I have a class named "Component" in a package named "test" (attached). This class defines a single getter method (getData()).

When I specify "test.Component" as the class to be introspected, I am getting the following wrong result, which looks more like the result of introspecting
"java.awt.Component":

  java Introspect test.Component
  class: test.Component
  pd.length: 7
  0:
  public java.awt.Color java.awt.Component.getBackground()
  class java.awt.Color
  1:
  public boolean java.awt.Component.isEnabled()
  boolean
  2:
  public boolean java.awt.Component.isFocusable()
  boolean
  3:
  public java.awt.Font java.awt.Component.getFont()
  class java.awt.Font
  4:
  public java.awt.Color java.awt.Component.getForeground()
  class java.awt.Color
  5:
  public java.lang.String java.awt.Component.getName()
  class java.lang.String
  6:
  public boolean java.awt.Component.isVisible()
  boolean

However, when i specify "test.component" (with a lower-case 'c') as
the class to be introspected, I get the expected result:

  java Introspect test.component
  class: test.component
  pd.length: 2
  0:
  public final native java.lang.Class java.lang.Object.getClass()
  class java.lang.Class
  1:
  public java.lang.String test.component.getData()
  class java.lang.String

Introspecting "test.Color" (with upper-case 'C') also seems to work as
expected:

  java Introspect test.Color 
  class: test.Color
  pd.length: 2
  0:
  public final native java.lang.Class java.lang.Object.getClass()
  class java.lang.Class
  1:
  public java.lang.String test.Color.getData()
  class java.lang.String
