PK18674: INCORRECT EXCEPTION THROWN ON STRING TO BIGDECIMAL CONVERSION

APAR status

• Closed as program error.

Error description

• Converting the String '.' (single dot) into BigDecimal
  throws a StringIndexOutOfBoundsException instead of a
  NumberFormatException
  java.lang.StringIndexOutOfBoundsException: String index out
  of range: 1
  at java.lang.String.charAt(String.java(Compiled Code))
  at java.math.BigDecimal.<init>(BigDecimal.java:310)
  at dectest.convert(dectest.java:14)
  at dectest.main(dectest.java:6)
  

Local fix

Problem summary

• java.lang.StringIndexOutOfBoundsException: String index out
  of range: 1
  was thrown when an attempt is made to convert a String
  containing a single dot into BigDecimal.  This was because
  Without checking the length of the String, the next element
  in the String was being accessed.
  

Problem conclusion

• The constructor of BigDecimal is changed to properly check
  the length of the String, and if the String contains only a
  single dot, then NumberFormatException is thrown.
  .
  To obtain the fix:
  Install build 20060209 or later
