Please review a minor but long-standing bug in the code to "compress" long strings in the `doctree` `DocCommentTester` class.
The primary change is in `DocCommentTester`, to fix the code, and make it somewhat more robust. The change does break some golden output, in comments and files, so advantage is taken to increase the max size of compressed strings. ------------- Commit messages: - JDK-8301810: Bug in doctree DocCommentTester.compress Changes: https://git.openjdk.org/jdk/pull/12418/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=12418&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8301810 Stats: 22 lines in 13 files changed: 4 ins; 0 del; 18 mod Patch: https://git.openjdk.org/jdk/pull/12418.diff Fetch: git fetch https://git.openjdk.org/jdk pull/12418/head:pull/12418 PR: https://git.openjdk.org/jdk/pull/12418
