Endless loop when using Double.parseDouble(String) with certain types of value
------------------------------------------------------------------------------

         Key: HARMONY-329
         URL: http://issues.apache.org/jira/browse/HARMONY-329
     Project: Harmony
        Type: Bug

  Components: Classlib  
    Reporter: Sian January


Calling Double.parseDouble(..) with certain Strings (e.g. Double.parseDouble("-1.233999999999999965116738099630936817275852021384209929081813042837802886790127428328465579708849276001782791006814286802871737087810957327493372866733334925806221045495205250590286471187577636646208155890426896101636282423463443661040209738873506655844025580428394216030152374941053494694642722606658935546875E-112");)
causes an endless loop.  

Although this is not necessarily a case you would see in regular programming it happens when
you do something like new BigDecimal(-1.234E-112).doubleValue(), which was the cause of the
endless loop mentioned in HARMONY-319.

The loop occurs in the native method "doubleAlgorithm (JNIEnv * env, U_64 * f, IDATA length,
jint e, jdouble z)" in native-src/shared/math/dblparse.c.
