/* SunVersion is used to compare java versions based on a string, as taken
from the registry. The strings look like "1.3", "1.3.1", "1.3.1_02" etc.
Versions such as "1.4.1_01a" are allowed although this is not specified.
1.4.1_01 < 1.4.1_01a < 1.4.1_01b < 1.4.1_02
Pre - release versions, such as 1.4.1-ea, 1.4.1-beta, 1.4.1-rc are recognized,
but are treated as minor to release versions:
1.4.0 > 1.4.2-beta
Pre releases relate this way
1.4.1-ea < 1.4.1-beta < 1.4.1-rc1
This class supports also a FreeBSD Java. This is currently necessary because
it also has the vendor string "Sun Microsystems Inc.".
An object acts as holder for the version string. That string may be present
even if the version could not be parsed. Then the version may not be compatible
to a SUN Java version.
An invalid object, that is, operator bool returns false, will always be
the lower version in a comparison. If two invalid objects are compared
then they are considered equal.
To test if the version is ok, that is this object can be compared to others,
use the bool conversion operator.
