public Object visit(ASTLoopStatement node,
           Object data)

PL/SQL does not have a do/while statement or repeat/until statement: the equivalent is a LOOP statement. A PL/SQL LOOP statement is exited using an explicit EXIT ( == break;) statement It does not have a test expression, so the Java control processing (on the expression) does not fire. The best way to cope it to push a DO_EXPR after the loop.

visit

public Object visit(ASTWhileStatement node,
           Object data)

A PL/SQL WHILE statement includes the LOOP statement and all Expressions within it: it does not have a single test expression, so the Java control processing (on the Expression) fires for each Expression in the LOOP. The best way to cope it to push a WHILE_LAST_STATEMENT after the WhileStatement has been processed.
