Convert and tidy-up unit tests in test/jaxp/javax/xml/jaxp/unittest/stream.
It is recommended to set the diff settings in github to hide whitespace (cog-wheel menu). There are a lot of cases where manual catch blocks with explicit fail are removed to just allow the test to fail idiomatically by throwing the exception normally. This causes thousands of lines to be un-indented (with no other change). There are also several non-trivial changes in this PR related to badly written tests where, for example, catching and ignoring exceptions allows the test to pass under all situations. ------------- Commit messages: - pre-review tidying - Convert to JUnit Changes: https://git.openjdk.org/jdk/pull/30643/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=30643&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8381882 Stats: 5002 lines in 86 files changed: 386 ins; 2050 del; 2566 mod Patch: https://git.openjdk.org/jdk/pull/30643.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/30643/head:pull/30643 PR: https://git.openjdk.org/jdk/pull/30643
