Comment 2 Martin Entlicher 2007-06-21 11:31:42 UTC 
This looks like a bug in com.sun.tools.javac.api.JavacTrees.
The problem is, that SourcePositions.getStartPosition(CompilationUnitTree, Tree) returns 1918, but
SourcePositions.getEndPosition(CompilationUnitTree, Tree) returns -1.
This is a bug, right?
Comment 3 Jan Lahoda 2007-06-22 14:37:22 UTC 
I tested this, and the tree for which the positions are returned is the synthetic "super();" constructor call (which is
not part of the source code, but is in the tree). Sorry, but you will need to check for it somehow:
-using TreeUtilities.isSynthetic (TreePath is currently needed for this method, a method taking only Tree may be
introduced later)
-check for -1 positions (to that reliable, but you do not need TreePath)
Comment 4 Martin Entlicher 2007-06-25 17:56:14 UTC 
It looks like TreeUtilities.isSynthetic() does not work then.
I've added condition for: ci.getTreeUtilities().isSynthetic(ci.getTrees().getPath(cu, node))
But it returns false for super();
TreeUtilities.isSynthetic() does not count with METHOD_INVOCATION kind.
