Improvement	Fix error-prone UnnecessaryParentheses by default	palantir/gradle-baseline#952
Improvement	Implement Error Prone ThrowError to discourage throwing Errors in production code Errors are often handled poorly by libraries resulting in unexpected behavior and resource leaks. It's not obvious that 'catch (Exception e)' does not catch Error. This check is intended to be advisory - it's fine to @SuppressWarnings("ThrowError") in certain cases, but is usually not recommended unless you are writing a testing library that throws AssertionError.	palantir/gradle-baseline#957
Improvement	Improve TestCheckUtils.isTestCode test detection	palantir/gradle-baseline#958
Improvement	Implement Error Prone Slf4jLevelCheck to validate that slf4j level checks agree with contained logging.	palantir/gradle-baseline#960
