GWT-Jep compatibility

GWT-Jep is mostly compatible with the Jep 4.1 release, apart from the following changes:

• Only the ConfigurableParser and StandardConfigurableParser are supported and not the JavaCC based StandardParser.
• There is no support for Serialization, the SerializableExpression class has been removed, and some serialization specific methods have been removed.
• Since Java 9 the java.util.Observable has been deprecated. Code using Observable mechanism has been removed.
• Some method names have been changed to correct spelling errors.
• Javascript has no integer datatype so any calculations that would use integers are performed as doubles.
• Not all the standard Java API is provided by GWT, see JRE Emulation
  • Simple re-implementations some of the missing classes, like BufferedReader are provided in the com.singularsys.compatibility package.
  • Google compatibility classes com.google.gwt.i18n.client.NumberFormat, used.
  • Simple re-implementations of Pattern and Matcher are provided these only implement the Matcher.lookingAt() method and not Matcher.find(). These use com.google.gwt.regexp.shared.RegExp class.
  • Some change in the format of message in Exceptions.
• New line character in parsed expression assumed to be \n
• The methods com.singularsys.jep.functions.BinaryFunction.instanceOf(Class<T>, BiFunction<T, T, ? super Object>) and com.singularsys.jep.functions.UnaryFunction.instanceOf(Class<T>, Function<T, ? super Object>) do not work.
• The JepMessages is re-implemented to use GWT Messages mechanism.
• com.singularsys.jepexamples.consoles.Console and other consoles do not read from the standard input. The com.singularsys.client.GWTConsole allows input from a text field.
• Some change in in messages in the com.singularsys.jepexamples.diagnostics format
• The JUnit tests in com.singularsys.jeptests generally do not currently work, hopefully fixed in next release
