The code below generates different exceptions on JAI_1.1.2 and JAI_1.1.1:

import javax.media.jai.LookupTableJAI;
public class Bug_GetFloatData_i_37 {
    public static void main(String args[]) {
       LookupTableJAI ltj = new LookupTableJAI(new float[]{1f, 2f});
       ltj.getFloatData(1);
    }
}

On JAI_1.1.2, we see RuntimeException.
But on JAI_1.1.1, we see ArrayIndexOutOfBoundsException.
LookupTableJAI.getDoubleData(1) has the same problem also.

On JAI_1.1.2:
Exception in thread "main" java.lang.RuntimeException: Cannot invoke DataBuffer method "getData".
        at com.sun.media.jai.util.DataBufferUtils.invokeDataBufferMethod(DataBufferUtils.java:141)
        at com.sun.media.jai.util.DataBufferUtils.getDataFloat(DataBufferUtils.java:221)
        at javax.media.jai.LookupTableJAI.getFloatData(LookupTableJAI.java:603)
        at Bug_GetFloatData_i_37.main(Bug_GetFloatData_i_37.java:7)


On JAI_1.1.1:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException
        at javax.media.jai.DataBufferFloat.getData(DataBufferFloat.java:155)
        at javax.media.jai.LookupTableJAI.getFloatData(LookupTableJAI.java:602)
        at Bug_GetFloatData_i_37.main(Bug_GetFloatData_i_37.java:7)

N/A

This is caused in DataBufferUtil:
Exception in thread "main" java.lang.RuntimeException: Cannot invoke DataBuffer method "getData".
        at com.sun.media.jai.util.DataBufferUtils.invokeDataBufferMethod(DataBufferUtils.java:165)
        at com.sun.media.jai.util.DataBufferUtils.getDataFloat(DataBufferUtils.java:245)
        at javax.media.jai.LookupTableJAI.getFloatData(LookupTableJAI.java:603)
        at Bug_GetFloatData_i_37.main(Bug_GetFloatData_i_37.java:5)

The exception type is not ducumented.  So ArrayOutOfBound is not required.  Suggest to change the test case.
