Sorry.
I am not subscribed to the list.
I Used the mail archive to check about the
problem

Because of firewall I can't use CVS.
However I downloaded via html CVS (I think this is how it is named)
the files which were at most 3 months old.
It still doesn't work properly.

Here  are some tests I did to verify if it is a bug:

Reg Exp:\s*(\d{1,2})\.(\d{1,2})(-(\d{1,2})\.(\d{1,2}))*(μμ|πμ)
Input: 7.00-9.00-11.00μμ

The output of matchResultExample is:
java -cp classes matchResultExample 
"\s*(\d{1,2})\.(\d{1,2})(-(\d{1,2})\.(\d{1,2}))*(μμ|πμ)" " 
7.00-9.00-11.00μμ"

Match:  7.00-9.00-11.00μμ
Length: 18
Groups: 7
Begin offset: 0
End offset: 18
Groups:
1: 7
Begin: 1
End: 2
2: 00
Begin: 3
End: 5
3: -11.00
Begin: 10
End: 16
4: 11
Begin: 11
End: 13
5: 00
Begin: 14
End: 16
6: μμ
Begin: 16
End: 18

The -9.00 is lost and -11.00 exists in three different groups.

If I tried input: 7.00-9.00-11.00-12.30μμ
The result is:
Match:  7.00-9.00-11.00-12.30μμ
Length: 24
Groups: 7
Begin offset: 0
End offset: 24
Groups:
1: 7
Begin: 1
End: 2
2: 00
Begin: 3
End: 5
3: -12.30
Begin: 16
End: 22
4: 12
Begin: 17
End: 19
5: 30
Begin: 20
End: 22
6: μμ
Begin: 22
End: 24

All the matches except the last one are lost in the 3 group.

As a workaround I used this pattern:
\s*(\d{1,2})\.(\d{1,2})((-\d{1,2}\.\d{1,2})*)(μμ|πμ)
group 3 will have in the above example string:-9.00-11.00-12.30
The String of the third group is sliced by an other regular expression.
