logBinaryDataFromInputStreamback to summary
private static final boolean logBinaryDataFromInputStream

For testing (otherwise false): When reading an InputStream from a Class or ClassLoader (that is, not from a file), log when the stream contains ICU binary data. This cannot be ICUConfig'ured because ICUConfig calls ICUData.getStream() to read the properties file, so we would get a circular dependency in the class initialization.

loggerback to summary
private static final Logger logger
PACKAGE_NAMEback to summary
pack-priv static final String PACKAGE_NAME

The ICU data package name. This is normally the name of the .dat package, and the prefix (plus '/') of the package entry names.
