The Eclipse JDT member sorter compares method names and parameter type signatures with a java.text.Collator. Spotless' DefaultJavaElementComparator used String.compareTo instead, which can produce a different member order than Eclipse save actions for names that differ by case or locale-sensitive collation.

Update DefaultJavaElementComparator to use Collator for member name comparison and parameter type signature comparison so Spotless matches Eclipse JDT behavior more closely.

Adds a regression fixture which exposes the case-sensitive ordering difference.

Test: ./gradlew :lib-extra:test --tests com.diffplug.spotless.extra.java.EclipseJdtFormatterStepSpecialCaseTest --no-daemon --no-configuration-cache --console=plain
