+  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.

l0ng-ai	bf2427bd3a	feat(java): selectable Java formatting profiles (#680 ) Java formatting comes from jdtls' Eclipse formatter, whose defaults differ from the IntelliJ IDEA code style. Settings › Editor › Code Style › Java now offers a formatting profile: Default (unchanged), IntelliJ IDEA, or a custom Eclipse formatter XML (absolute or project-relative path). The IntelliJ IDEA profile is a bundled Eclipse formatter XML that follows IDEA's default Java code style item by item (indents, aligned multi-line parameters, annotation placement, else/catch/finally on the same line, array initializers, lambdas, blank lines, comments not reflowed). Manual line breaks are kept; lines longer than 120 columns wrap where necessary, which differs from IDEA's default of not wrapping. The profile reaches a running jdtls through didChangeConfiguration without a restart; an unreadable custom file shows a warning and leaves code intelligence running. Code style changes reconfigure language servers without scheduling Kotlin bridge builds. Also drops two catalog entries whose texts are no longer used. Fixes #649	2026-11-01 18:26:24 +08:00
