Logging APIs: StreamHandler constructor ignores encoding property

Name: elR10090 Date: 12/22/2000



Logging APIs implementation fails the test
nsk/logging/StreamHandler/StreamHandler/strmhnd003 from testbase_nsk.

The test checks if StreamHandler created with the constructor
StreamHandler() is configured correctly. That is handler level, filter,
formatter and encoding are initialized using the specified default values
when their properties are not defined and the expected values when their
properties are defined.

The test reveals that the constructor StreamHandler does not set
character encoding to a value difined by the property
java.util.logging.StreamHandler.encoding.

By the way, the Logging APIs spec (draft 0.55) doesn't explicitly state
the constructor to use LogManager properties (or their defaults) as it does
for ConsoleHandler, FileHandler, MemoryHandler and SocketHandler constructors.
I think the spec should document this by the same way.

Log and the test source follow:

$ java -version
java version "1.4.0beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0beta-b45)
Java HotSpot(TM) Client VM (build B45, mixed mode)

$ java logging.StreamHandler.StreamHandler.strmhnd003
# Wrong ".level" value "INFO", expected "ALL"
# Wrong ".encoding" value "null", expected "US-ASCII"
# TEST FAILED.
