Mitigate user prefs lock by bric3 · Pull Request #10231 · DataDog/dd-trace-java

bric3 · 2025-12-17T14:22:21Z

What Does This Do

Move the Gradle daemon user prefs location to a different location.

Motivation

Filing steps, due to user preferences locking contention.

Symptom:

Couldn't flush user prefs: java.util.prefs.BackingStoreException: Couldn't get file lock.

User preferences are still a bottleneck for some steps, in particular the 5/6 slot for instrumentation tests.

Analysis
This is still happening, the reason is that on Linux, the Preferences backend is a FileSystemPreferences.

Whoever request the user preferences, trigger the following automatic flush mechanism, that will happen

Every 30 seconds via a timer (java.util.prefs.syncInterval property, default 30s)
On shutdown

Gradle is configured to have 4 active parallel workers via the --max-workers flag (otherwise the default would be 10, the number of requested CPU). Possibly they are started around the same time and contend on this lock.

Who is writing there
Groovy !

~/.java/.userPrefs
├── .user.lock.non-root-user
├── .userRootModFile.non-root-user
└── org
├── codehaus
│ ├── groovy
│ │ ├── tools
│ │ │ └── shell
│ │ │ │ └── prefs.xml
│ │ │ └── prefs.xml
│ │ └── prefs.xml
│ └── prefs.xml
└── prefs.xml

This is a follow-up of the mitigations in

Avoid preferences lock file contention for tests due to spawned child processes #10083
