Starting audit...
[ERROR] TestClass.java:3:74: '}' at column 74 should be alone on a line. [RightCurly]
Audit done.
Checkstyle ends with 1 errors.
74 is a position of } for method finalize
Expected: 2 violations on line 3 (column 74 and 89).
89 is a position of } for anonymous class;
} int b = 10; } this two } should be violated.
Note that shouldStartLine (false, true) does not affect the logic. So the problem is in shouldBeAloneOnLine.
