Statement
ForInit:

ForUpdate:
Expression { , Expression }
Note: When variables are declared in the initializer
of a for statement such as "for (int a=1, b=2;;);",
they should be represented as a single
VariableDeclarationExpression
with two fragments, rather than being split up into a pair
of expressions.

The list should consist of either a list of so called statement
expressions (JLS2, 14.8), or a single VariableDeclarationExpression.
Otherwise, the for statement would have no Java source equivalent.

Special note: The Java language does not allow a local variable declaration
to appear as the body of a for statement (they may only appear within a
block). However, the AST will allow a VariableDeclarationStatement
as the body of a ForStatement. To get something that will
compile, be sure to embed the VariableDeclarationStatement
inside a Block.
