[jira] Created: (HARMONY-329) Endless loop when using
Double.parseDouble(String) with certain types of value
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.
