Description Matthieu Helleboid CLA 2005-05-25 16:26:55 EDT 
If you call getJavaElement() on a VariableDeclarationFragment which is part of a    
VariableDeclarationExpression you'll get a ClassCastException.    
 
In org.eclipse.jdt.core.dom.VariableBinding.getUnresolvedJavaElement 
"VariableDeclarationStatement statement = (VariableDeclarationStatement)  
localVar.getParent();" is a useless and a bad cast because localVar.getParent() could be a 
VariableDeclarationExpression. 
   
For example in "For(int i=0;..."   
"int i=0" is a VariableDeclarationExpression   
"i=0" is a VariableDeclarationFragment   
If you do "i=0".resolveBinding().getJavaElement(), you'll get a ClassCastException.
