KLS is built on IntelliJ's platform, which by default creates a new ~52 MB idea-system<random>/ directory in /tmp for each instance. These directories are never cleaned up on shutdown. On tmpfs systems (the default on modern Linux) this causes unbounded RAM consumption — e.g. 329 accumulated directories totalling 30 GiB after repeated test runs. Fix: append -Didea.system.path=<ls_resources_dir>/kotlin_language_server/system/ to JAVA_TOOL_OPTIONS in create_launch_command_env(). This redirects IntelliJ to a fixed, bounded per-project cache directory that also persists across sessions for faster restarts. Fixes oraios#1087 Co-Authored-By: Claude <noreply@anthropic.com>

self._ls_resources_dir is already specific to the Kotlin LS.

Summary
Fixes #1087
The Kotlin Language Server (KLS) is built on IntelliJ's platform, which by default creates a new
idea-system<random>/directory in/tmpfor each instance. These directories are never removed on shutdown, causing unbounded accumulation.On
tmpfssystems (the default on modern Linux), this means unbounded RAM consumption — the issue author observed 329 stale directories totalling 30 GiB after repeated test runs.Fix
In
DependencyProvider.create_launch_command_env(), append-Didea.system.path=<ls_resources_dir>/kotlin_language_server/system/toJAVA_TOOL_OPTIONS. This redirects IntelliJ to a fixed, per-project location instead of/tmp/idea-system<random>/.The chosen location (
ls_resources_dir/kotlin_language_server/system/) is:/tmpChanges
src/solidlsp/language_servers/kotlin_language_server.pycreate_launch_command_env(): computesystem_dir, create it, and append-Didea.system.pathtoJAVA_TOOL_OPTIONSTesting
The fix can be verified by running the Kotlin language server tests and confirming that no new
idea-system*directories appear in/tmpduring the test run, while<ls_resources_dir>/kotlin_language_server/system/is populated instead.🤖 Generated with Claude Code
