  - ensureLargeEnough
```

  - ensureLargeEnough
```
public static java.nio.ByteBuffer ensureLargeEnough(java.nio.ByteBuffer buffer,

  - printCurrentDirectMemory
```
public static void printCurrentDirectMemory(java.lang.StringBuilder store)
```
  - destroyDirectBuffer
```
public static void destroyDirectBuffer(java.nio.Buffer toBeDestroyed)
```
    Direct buffers are garbage collected by using a phantom reference and a reference queue. Every once a while, the JVM checks the reference queue and cleans the direct buffers. However, as this doesn't happen immediately after discarding all references to a direct buffer, it's easy to OutOfMemoryError yourself using direct buffers.
    
    Parameters:
    
    toBeDestroyed - the buffer to de-allocate (not null)
