I expected no warning because of section 4.1.3 Empty blocks: may be concise in Google Java Style Guide.
An empty block or block-like construct may be in K & R style (as described in Section 4.1.2). Alternatively, it may be closed immediately after it is opened, with no characters or line break in between ({}), unless it is part of a multi-block statement (one that directly contains multiple blocks: if/else or try/catch/finally).
Problem exists since Checkstyle 8.20, with Checkstyle 8.19 there is no such warning.
