-  IntelliJ IDEA Java defaults, approximated using Eclipse JDT formatter options.

-  platform/code-style-api/src/com/intellij/psi/codeStyle/CodeStyleSettings.java
-  platform/code-style-api/src/com/intellij/psi/codeStyle/CodeStyleDefaults.java
-  java/java-frontback-impl/src/com/intellij/psi/codeStyle/JavaCodeStyleSettings.java
-  JavaLanguageCodeStyleSettingsProvider.customizeDefaults does not override these values.
-  https://www.jetbrains.com/help/idea/code-style-java.html describes the corresponding controls.
-  Each option below names its IDEA setting; JDT has no exact equivalent for every rule.
-  A formatter profile does not sort/group imports (Organize Imports is a separate action).
-  Preserve IDEA KEEP_LINE_BREAKS=true using Wrap where necessary (WRAP_COMPACT) and
-  join_wrapped_lines=false (Never join already wrapped lines). JDT NO_SPLIT joins some
-  manual parameter/call/chain breaks even when joining is disabled. Preserving manual
-  breaks takes priority: wrappable code exceeding 120 columns will also wrap, a known
-  difference from IDEA defaults (DO_NOT_WRAP / WRAP_LONG_LINES=false).
-  Alignment values: 16 = WRAP_COMPACT + INDENT_DEFAULT; 18 = WRAP_COMPACT + INDENT_ON_COLUMN.
-  The comment width 999999 approximates WRAP_COMMENTS=false without JDT integer overflow.
-  JDT has a shared blank-line preservation limit and different empty-body/Javadoc handling.
