Strange exception while dealing with strings

[vanjajovic@xxxxxxxxxxxx (Vanja Jovic)]

Hi, all

this is what I get in string intensive application while handling large files.
Doesn't happen all the time and doesn't happen at the same place. Any ideas?

java.lang.UnknownError
      sun/io/CharToByteISO8859_1.convert([CII[BII)I+236 
(CharToByteISO8859_1.java:103)
      sun/io/CharToByteConverter.convertAny([CII[BII)I+27 
(CharToByteConverter.java:142)
      java/lang/String.getBytes(Lsun/io/CharToByteConverter;)[B+40 
(String.java:629)
      java/lang/String.getBytes(Ljava/lang/String;)[B+5 (String.java:665)
      Inv2PDF.main([Ljava/lang/String;)V+146 (Inv2PDF.java:91)

It gets worse the higher optimization level it is.

thks,

Vanja
