             Summary: DiffRepository generation xml doesn't respect 
alphabetical order
                 Key: CALCITE-7261
                 URL: https://issues.apache.org/jira/browse/CALCITE-7261
             Project: Calcite
          Issue Type: Bug
          Components: testkit
            Reporter: Sergey Nuyanzin
            Assignee: Sergey Nuyanzin


Especially often reproduced for existing empty files.
For instance current expected is empty or absent (might be a case if just want 
to regenerate from scratch)

then if a class has methods
{code:java}
  @Test void testDiff() {
    ...
  }

  @Test void testmulti() {
      ...
  }

  @Test void testNull() {
      ...
  }
{code}

Here {{testmulti}} was intentionally written in lowercase to highlight another 
issue. While generation it compares names with ignoring case. At the same side 
while sorting in {{DiffRepository}} it uses lexicographical order without 
ignoring of case.

So as a result generated xml for the class with methods above might result in a 
variety of versions and not stable.
