FlexPMD Outline view not working - throwing an error

For some reason the FlexPMD is throwing error when I open FlexPMD Outline.

My environment:

Windows 7 64 bit

Flex Builder 3.0.2 Standalone

FlexPMD 1.0.1

The error is:

Error creating the view.
org.eclipse.ui.IMemento.getBoolean(Ljava/lang/String;)Ljava/lang/Boolean;

When I click OK, it shows the Outline Window but it displays Error creating the view. Here are the full details:

java.lang.NoSuchMethodError: org.eclipse.ui.IMemento.getBoolean(Ljava/lang/String;)Ljava/lang/Boolean;
