This line to be removed simply because `EndPosTable` no longer has this back-reference to the parser. This file is used in a test for [JDK-8067384](https://bugs.openjdk.org/browse/JDK-8067384) which verifies that it's possible to subclass `JavacParser`.

My assumption was that this line was just a cut & paste copy of [this line](https://github.com/openjdk/jdk/blob/94039e22bbe943888e858d8ae278145e2668526a/src/jdk.compiler/share/classes/com/sun/tools/javac/parser/JavacParser.java#L4144) and has no significance to the actual test.
