[GoogleCodeExporter]

What steps will reproduce the problem?
1.Run the Main.java file attached

What is the expected output? An array
What do you see instead? ArrayIndexOutOfBoundsException

What version of the product are you using? bsh-2.1.8
On what operating system? Windows XP + Java 1.7.71

Please provide any additional information below.

Hi,
I'm running some Genetic Programming (GP) experiments. GP auto-generates lots 
of programs to be run by BeanShell. The majority run correctly, but 1% give 
ArrayIndexOutOfBoundsException in Reflect.getIndex() for no apparent reason.
Please run the attached Main.java file.

Same stuff happens with the inputs (just to give some examples):

expression = 
"i=0;j=0;temp=0;time=System.currentTimeMillis();for(j=0;j<array.length;j++){if((
System.currentTimeMillis()-time)>1000)return 
null;if(j<array.length&&i<array.length){temp=array[i];array[i]=array[j];array[j]
=temp;}if(j<array.length&&i<array.length){temp=array[i];array[i]=array[j];array[
j]=temp;}}for(i=0;i<array.length;i++){if((System.currentTimeMillis()-time)>1000)
return 
null;if(j<array.length&&i<array.length){temp=array[i];array[i]=array[j];array[j]
=temp;}}if(array[i]<array[i]){if(j<array.length&&i<array.length){temp=array[i];a

I've tried this with bsh-2.1.8, bsh-2.0b5, bsh-2.0b4 and bsh-1.3.0 allways 
giving the same ArrayIndexOutOfBoundsException.
If anyone can help, I'll appreciate a lot.
Best regards,
David

Sorry, It was my mistake.

Alter the for(int i=0;i<array.length;i++) the i is array.length, so if i use it 
in array[i] it is out of bounds.

Sorry to bother.
Thanks,
David
