java-debug runs inside jdtls and is reached through its debugServer port, but configurations that aren't Application / Spring Boot and select java-debug (a Shell Script running `catalina.bat run`, say) fell through to the generic launch template, and the adapter launcher tried to start com.microsoft.java.debug.plugin.jar as a process: on Windows that failed with os error 193, elsewhere with a misleading "debug adapter not found". - Shell script / program configurations with java-debug start with a suspended JDWP agent injected through JAVA_TOOL_OPTIONS and attach once the JVM prints its port, so `catalina.bat run` / `catalina.sh run` can be debugged. - Maven goals that run the app in Maven's JVM (tomcat7:run, jetty:run(-war), exec:java, or any Maven config with java-debug) are debugged through MAVEN_OPTS. - Gradle tasks that start no JVM say why they can't be debugged; `debug.startConfig` with a single debuggable config goes through the run debug flow. - .jar adapters are never spawned as processes, and Windows adapter lookup only accepts PATHEXT files (so npm-installed adapters pick the .cmd shim instead of the POSIX one); the PATHEXT expansion moves to ide_core::process::executable_names, shared with ide-run. Not run on Windows; the Windows resolution is covered by tests with an injected platform. Fixes #179 Claude-Session: https://claude.ai/code/session_01Dq6jQQn8ZhRfkkyj3PRutA

OpenIDEA brings the IntelliJ IDEA way of working — its keymap, its tool windows, its search-everything habits — to a native app with a Rust core.
Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.
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.
