If the default provider package provides an implementation of the
specified CertPathBuilder
algorithm, an instance of
CertPathBuilder
containing that implementation is returned.
If the requested algorithm is not available in the default package,
other packages are searched.

public static final String getDefaultType()
CertPathBuilder
type as specified in
the Java security properties file, or the string "PKIX"
if no such property exists. The Java security properties file is
located in the file named <JAVA_HOME>/lib/security/java.security,
where <JAVA_HOME> refers to the directory where the SDK was
installed.
The default CertPathBuilder
type can be used by
applications that do not want to use a hard-coded type when calling one
of the getInstance
methods, and want to provide a default
type in case a user does not specify its own.
The default CertPathBuilder
type can be changed by
setting the value of the "certpathbuilder.type" security property
(in the Java security properties file) to the desired type.
