Root cause: every java launch inlined the whole classpath into one -cp argument with no "Shorten command line", so long classpaths exceeded CreateProcessW's 32767-char limit (os error 206) before the JVM started.
Fix (IDEA's auto "Shorten command line"): ide-run rewrites a too-long java command line at spawn time — @argfile on JDK 9+ with ASCII paths, otherwise a MANIFEST pathing jar (percent-encoded file: URLs, 72-byte lines); temp files are removed when the process exits. Debug passes the same choice to java-debug's shortenCommandLine.
Siblings covered: Application/Spring Boot, test classpath, Kotlin main, explicit java -cp configs, profiler, PTY launches, Debug.
Verified: unit tests, pathing jar loaded by real JDK 8/11/25, ProcessManager integration test with 3000 entries on JDK 8/17/25. Not verified on Windows.

* feat: Second pass aligning interactions with IntelliJ IDEA
Result tool windows
- Next/Previous Occurrence (⌥⌘↓/↑) across Find, Usages, Problems, TODO,
Inspection and Hierarchy, with an "N of M" status hint
- Find: reuse the unpinned tab, Pin Tab, source preview, group by file or
directory, exclude moves to the next result, Rerun
- Usages: tabs with pinning, exclude and preview
- Problems, TODO, Inspection: no autoscroll by default, severity-first sorting,
context menu with quick fixes and copy description
- Trees: F4/⌘↓ jump to source; speed search Home/End and arrow handling
Find in Files, bookmarks, navigation
- Replace mode: Enter replaces the selection, ⇧⌥Enter replaces all, multi-select
- Pin Window toggle, highlighted read-only preview, search/replace history (⌥↓),
Alt mnemonics, search context filter (comments / string literals)
- Mnemonic bookmarks (⌥F3, ⌃⇧digit, ⌃digit), ⌘F3 bookmarks popup, descriptions,
⌘-click gutter toggles a bookmark

Code insight and refactoring
- Extract/Introduce continue with in-place rename and name suggestions;
expression and occurrence choosers with live highlighting
- Safe Delete confirms first; numbered Refactor This
- Quick Documentation history, in-popup links and a Documentation tool window;
Quick Definition switches between targets and shows the whole declaration
- Goto chooser lists symbol names and can pin to the Find window

in and out of blocks and re-indents
- Type over closing quotes of existing strings; ⌘D/⌘⌫ cover folded regions;
⌥⌫ deletes the preceding word

Run, VCS, workbench
- Gutter icons show the last test result; Modify Run Configuration; test tree
hides passed tests, context menu and assertion diff
- Stack frames resolve by fully qualified class name; context run chooser
- Inline Smart Step Into
- Git Log multi-select filters, "me" and date range; favourite branches,
Fetch and tags in the branch popup; stash Keep index and Unstash options
- Terminal tab titles follow the shell; Distraction Free persists; gear menu;
sticky balloons move to the notifications tool window after a while
* fix(vcs): Label restored local changes as yours after Smart Checkout; name the branch checked out
Conflicts from restoring stashed changes show the user's uncommitted
changes on the left like other operations, and the checkout notification
names the new branch instead of the previous one.
* fix: Close the merge editor on Apply; confirm before terminating a running Run tab
Like IDEA, applying a merge result closes its tab, and closing a Run tab
whose process still runs asks before terminating it (with a Settings
toggle and "Do not ask again").
* fix(terminal): Don't start a new session in the background after closing the last tab
The hidden Terminal window stays mounted, so it reopened a session as soon
as the last tab closed. It now opens the Local tab only once the window is
shown again, as IDEA does.
* fix(vcs): Start the merge result from a three-way merge; close the editor on Apply
The result pane now begins with non-conflicting changes merged and each
conflict showing the base text, resolved from the side panes, instead of
raw conflict markers. Apply now reports success, so the tab closes.
fix(search): Match File Structure filter on word starts
* fix: Limit Smart Step Into to the paused line; drop usages hints on callbacks; show full intention titles
Adapters that list every remaining call in the function (debugpy) made Smart
Step Into fall back to a chooser that offered calls from later lines. Targets
are now narrowed to the calls on the paused line, so they are picked in place.
Anonymous functions and callbacks no longer get a 'no usages' hint, and
intention titles are no longer cut short when there is room for them.
* fix: Undo / Redo from the Edit menu and Find Action use the editor's history
They ran the webview's native undo, which misses programmatic edits such as
templates, completion and refactorings, so nothing happened in the editor.
* fix(java): Run jdtls with a Lombok agent and show build errors at launch
jdtls compiles with ECJ, which only generates Lombok members when the
server JVM runs -javaagent:lombok.jar. Nothing put it there, so @Data /
@Setter classes lost their accessors and Run launched stale classes
with "Unresolved compilation problem" stubs and no explanation.
- Projects whose build files mention Lombok get the newest jar: the
IDE-managed one (new "Lombok (jdtls agent)" tool, latest release from
Maven Central), else ~/.m2 (incl. settings.xml localRepository) or the
Gradle cache. Each agent gets its own jdtls workspace so everything is
rebuilt with it.
- Settings › Languages & Frameworks › Java › JVM options
(java.jdt.ls.vmargs); a Lombok agent there wins.
- Run (and Debug, as a notification) list the first compile errors when
the build has errors, plus a hint when Lombok is missing or older than
1.18.34.
Fixes#3
* fix(java): Base the Lombok hint on the agent jdtls actually runs
A Lombok agent in Settings › Java › JVM options wins over the managed
and cached jars, but the launch hint still looked only at those: with
no cached jar it said Lombok was missing, and with an old cached one it
blamed that version although jdtls ran the user's. The hint and the
startup warning now use the user's agent (version from its file name).
