Stack Overflow Error while parsing a long String

["Sinha, Sahasrangshu(Anshinsoft)" <sa...@anshinsoft.com>]

Hi,
  We use regexp package in our application. We have encountered an error
while parsing a long string (with over than 8000 characters) as a value
of a tag during SWIFT processing.

encountered exception
java.lang.StackOverflowError
 at org.apache.regexp.StringCharacterIterator.charAt(Unknown Source)
 at org.apache.regexp.RE.matchNodes(Unknown Source)

Is there any environmental remedy required (i.e. increasing Stack size of
JVM) or is it incapability of regexp to parse long string?

Thanks in advance for your valuable comments or suggestion.

Best Regards,
Sahasrangshu

Yes.
