[OOM][Thread:  0x00062fd0]<Tue Dec 2 16:42:39 2003>
[java.lang.OutOfMemoryError :   requested 1024 bytes. (Java Heap) : 
20 threads exist]

Notes

In the following cases, the requested memory size cannot be collected:

• When the Java memory allocation functionality is not used and an OutOfMemoryError (including errors thrown by the J2SE class library) is explicitly thrown.

  Example:

  throw new OutOfMemoryError();

• When an OutOfMemoryError is caused by verifier during class loading.
