 Description   

I set ReconnectInterval in the DEFAULT section to the same string as the example in QFJ-419
ReconnectInterval=6*5;5*15;60

When I run the program I get the following stack trace

quickfix.ConfigError: java.util.regex.PatternSyntaxException: Dangling meta character '*' near index 0

Could you try if it works when specifying "x" as the multiplier character?
Anyway, there seems to be a bug when using "*" as multiplier.

Seems it was forgotten to escape the asterisk when parsing the parameters. But as said, it should also work with "x" as separator.
