Cascade Generated Code with Memory Leak

Memory usage continuously increases after Cascade generated new code. Application eventually runs out of memory and crashes. Heap analysis shows objects are not being garbage collected even after they're no longer needed.

Cascade likely created resource holders or listeners that are never cleaned up.

Error Messages You Might See

OutOfMemoryError: Java heap space Memory continuously grows during normal operation GC overhead limit exceeded Heap dump shows retained objects
OutOfMemoryError: Java heap spaceMemory continuously grows during normal operationGC overhead limit exceededHeap dump shows retained objects

Common Causes

  1. Cascade added listeners or subscribers without removing them (Observer pattern memory leak)
  2. Circular references between objects preventing garbage collection
  3. Static collections that grow indefinitely without cleanup
  4. Cascade generated code that doesn't close resources (streams, connections)

How to Fix It

Use Java Flight Recorder or Eclipse MAT to analyze heap dumps. Look for growing object counts. Implement proper resource cleanup: try-with-resources for streams, close connections, unregister listeners. Use weak references for caches. Test with long-running load tests to identify memory growth.

Frequently Asked Questions

How do I detect memory leaks?

Monitor heap usage with JConsole or Grafana. Generate heap dump on OOM: -XX:+HeapDumpOnOutOfMemoryError. Analyze with Eclipse MAT.

What causes memory leaks in Java?

Unclosed resources, static collections, listeners not unregistered, circular references, classloader leaks.
