Using eclipse-SDK-3.0RC1-win32.zip.

I'm trying to create an AST tree from a snippet of Java code using code like this:

String src = "\tSystem.out.println(\"Hello\");\n\tSystem.out.println(\"World\");\n";
char[] source = src.toCharArray();
ASTParser parser = ASTParser.newParser(AST.JLS2);
parser.setKind (ASTParser.K_STATEMENTS);
parser.setSource (source);
ASTNode result = parser.createAST (new NullProgressMonitor());

The result I get back is always an empty block, and I would expect it to be a
block with two ExpressionStatements in it.

If I add one line of code before the parser.createAST call to set the source range:
   parser.setSourceRange(0, source.length);

then I get back a block with two ExpressionStatements in it.

According to the JavaDoc for 'setSourceRange':
"Sets the subrange of the source code to be parsed. By default, the entire
source string will be parsed (offset 0 and length -1)."

So from that text it seems that it is not required to set the source range.
It appears that the 'ASTParser.setSource (char[] source)' method should be
setting the source range or there is some other defect elsewhere when the
sourceLength == -1 is not being honoured.
