[PATCH 00/13] Clean up the Java skeleton and tests

[Akim Demaille]

Before porting the new ways to produce error message to the Java
skeleton, I encountered a few issues:

- the traces are different.  Sometimes the way the Java skeleton
  handles them is better, so, overall, all the traces have been
  revised to be more alike, and easier to follow.

- the Java code is sometimes inconsistent, and (uselessly?) hairy.
  Maybe it was addressing portability issues with real old versions of
  Java, I don't know, I'm definitely not familiar with Java.

- the calc test suite was forked twice for Java: once for pull
  parsers, and another time for push parsers.  That would have led to
  more testing efforts for parse.error, which I don't want.

This series of commits address these problems.  Comments would be most
welcome, especially from Java practitioners.

Akim Demaille (13):
  traces: write the "Reading a token" alone on its line
  traces: show the stack after reading a token
  traces: don't print the stack before the gotos
  java: examples: split in two
  java: examples: prefer switch to chains of else-if
  java: examples: fix the tracking of locations
  java: style: prefer putting the square brackets on the type
  java: style: avoid useless initializers
  java: tests: prepare the replacement of calculator tests
  java: tests: check location tracking in the calculator
  java: tests: remove now redundant tests
  java: tests: check push parsers
  java: tests: remove now redundant tests
