# BuildPlanExecutor: Thread pool leaked on constructor exception
**Found in:** maven-4.0.x branch
**File:**
`impl/maven-core/src/main/java/org/apache/maven/lifecycle/internal/concurrent/BuildPlanExecutor.java`
(line 214)
**Severity:** Medium
## Description
The `BuildContext` constructor creates a thread pool and then calls
`buildInitialPlan()`:
```java
BuildContext(MavenSession session, ReactorContext reactorContext,
List<TaskSegment> taskSegments) {
...
this.executor = new
PhasingExecutor(Executors.newFixedThreadPool(threads, new
BuildThreadFactory()));
this.plan = buildInitialPlan(taskSegments);
}
```
`buildInitialPlan()` is called inside the constructor, before the
`try-with-resources` in `execute()` begins. If `buildInitialPlan()` throws
(e.g., `PluginNotFoundException`, `LifecyclePhaseNotFoundException`), the
`BuildContext` constructor throws and `close()` is never called (the object was
never fully constructed), leaving the thread pool running indefinitely as a
resource leak.
