>      Project: Harmony

>   Components: Classlib

> 1) java.lang.StringBuilder.insert(int offset, char c):
> Harmony throws StringIndexOutOfBoundsException when offset <0,
> while RI throws ArrayIndexOutOfBoundsException. 
> Specification mentions neither StringIndexOutOfBoundsException
> nor ArrayIndexOutOfBoundsException throwing, but says: 
> "Throws:
> IndexOutOfBoundsException - if the offset is invalid".
> 2) java.lang.StringBuffer.append(char[] str, int offset, int len):
> Harmony throws StringIndexOutOfBoundsException when str is not
> null, offset or/and len <0, while RI throws
> ArrayIndexOutOfBoundsException. Specification mentions neither
> StringIndexOutOfBoundsException nor
> ArrayIndexOutOfBoundsException throwing.
> 3) java.lang.StringBuffer.append(char[] str, int offset, int len):
> Harmony throws StringIndexOutOfBoundsException when str = null,
> offset or/and len <0, while RI throws NullPointerException.
> Specification mentions neither StringIndexOutOfBoundsException
> nor NullPointerException throwing.
> 4) java.lang.StringBuffer.getChars(int srcBegin,int srcEnd,char[] dst, int dstBegin):
> Harmony throws StringIndexOutOfBoundsException when dstBegin <0,
> while RI throws ArrayIndexOutOfBoundsException.
> Specification says:
> "Throws: 
> IndexOutOfBoundsException - if any of the following is true: 
> ...
> dstBegin is negative". 
> So RI does not comply with spec as well as Harmony does not comply with it.
> 5) java.lang.StringBuffer.insert(int offset, char c):
> Harmony throws StringIndexOutOfBoundsException when offset <0,
> while RI throws ArrayIndexOutOfBoundsException.
> Specification says:
> "The offset argument must be greater than or equal to 0 ... 
> Throws: 
> IndexOutOfBoundsException - if the offset is invalid."
> So RI does not comply with spec as well as Harmony does not comply with it.
