Settings › Editor › Code Style › Java › Tabs and Indents had no effect on Reformat Code: a file indented with 4 spaces stayed that way after choosing "Use tab character" with tab size and indent 1. There were two causes. The reformat request sent the editor's indent, which comes from the indents detected in the file, instead of the Code Style; and jdt.ls takes the per-level indent width (`indentation.size`) only from its formatter profile, never from the request. With an explicit Tabs and Indents override for the language, Reformat Code now asks for the Code Style indent (EditorConfig still applies, the detected indents don't; without an override the editor's indent is kept). The jdt.ls profile carries the same override: it is patched into the bundled IntelliJ profile, or put into a minimal generated profile for the default formatter, and custom profiles are left alone. An unset Indent follows the tab size, as in Code Style. With tabs the request sends the tab size; every editor of a document gets the override when it is created, splits and reopened tabs included, not only after a settings change. Checked with jdt.ls 1.63 on JDK 25: tab character, tab size 1 and indent 1 reformat a 4-space file to one tab per level with both the default and the IntelliJ formatter. Fixes #935.

Benchmark
Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:
| OpenIDEA | IntelliJ IDEA 2026.2.3 | |
|---|---|---|
| Window with the project | 0.9 s | 3.1 s |
| Ready (CPU settled) | 1.1 s | 13.2 s |
| Memory (USS, all processes) | 169 MB | 2011 MB |
| CPU time until ready | 2.4 s | 47.9 s |
| Idle CPU | 4 % of a core | 7 % of a core |
| Quit | 0.3 s | 5.9 s |
A release build of OpenIDEA from main and IDEA with default settings and plugins, on
Windows 11, 32-core AMD, 62 GB RAM.
IDEA analyses Python more deeply, so "ready" doesn't mean the same work on
both sides. Both are measured from the outside, the same way: see
perf/compare to run it on your machine and projects.
