SYMPTOMS
In Microsoft Visual J# .NET 2003, when you use the String.hashCode method, you notice that the Visual J# implementation is slower than the Microsoft Visual C# implementation. Therefore, if you use the String.hashCode method frequently in your Visual J# .NET application, you may experience slow performance.



CAUSE
This problem occurs because the Visual J# implementation of the String.hashCode method performs a high volume of char[] allocations compared with the Visual C# implementation.
