> When I use JavaParser to parse a class containing imports of the form "import
> package.name.*", the parser fails on an IllegalStateException("Unknown token:
> 87"). Full test case below:
> File: JaxmeTest.java
> import java.io.FileReader;
> import org.apache.ws.jaxme.js.*;
> import org.apache.ws.jaxme.js.util.JavaParser;
> public class JaxmeTest {
> public static void main(String[] args) {
> JavaSourceFactory jsf = new JavaSourceFactory();
> JavaParser parser = new JavaParser(jsf);
> try {
> parser.parse(new FileReader("JaxmeTest.java"));
> } catch(Exception e) {
> e.printStackTrace();
> }
> }
> }
> Command line transcript:
> C:\workspace\EventMonitor3.0> javac JaxmeTest.java -cp
> lib\jaxmejs-0.5.jar;lib\antlr.jar
> C:\workspace\EventMonitor3.0> java -cp .;lib\jaxmejs-0.5.jar;lib\antlr.jar
> JaxmeTest
> java.lang.IllegalStateException: Unknown token: 87

> at

> org.apache.ws.jaxme.js.util.JavaParser.parseAST(JavaParser.java:457)
> at org.apache.ws.jaxme.js.util.JavaParser.parse(JavaParser.java:108)
> at org.apache.ws.jaxme.js.util.JavaParser.parse(JavaParser.java:80)
> at JaxmeTest.main(JaxmeTest.java:10)
> Looking through the source, it looks like the JavaParser.parseIdentifier()
> method called by parseImportStatement() expects the identifier to be a
> primitive or ordinary dotted identifier, but the grammar production used in
> java15.g is:
> identifierStar
> : IDENT
> ( DOT^ IDENT )*
> ( DOT^ STAR )?
> ;
> This may also have a STAR token, which falls through to the exception case.
> For my purposes, I'd be happy if it just ignored the * and didn't choke on
> the file.
