/**
* A common base class for frame modeling visitors.
* This class provides a default implementation which copies values
* between frame slots whenever appropriate. For example, its handler
* for the ALOAD bytecode will get the value from the referenced
* local in the frame and push it onto the stack. Bytecodes which
* do something other than copying values are modeled by popping
* values as appropriate, and pushing the "default" value onto the stack
* for each stack slot produced, where the default value is the one
* returned by the getDefaultValue() method.
* <p/>
* <p> Subclasses should override the visit methods for any bytecode instructions
* which require special handling.
* </p>
* <p>
* Users of AbstractFrameModelingVisitors should call the
* analyzeInstruction() method instead of directly using the accept()
* method of the instruction. This allows a checked DataflowAnalysisException
* to be thrown when invalid bytecode is detected. E.g.,
* stack underflows.
* </p>
