Subject [jira] Commented: (RIVER-82) ClassDep generates duplicate output lines
Date Thu, 26 Jul 2007 21:18:03 GMT

    [ https://issues.apache.org/jira/browse/RIVER-82?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12515871
] 

Fred Oliver commented on RIVER-82:
----------------------------------

For reasons not yet clear to me, sometimes BinaryConstantPool.getDependencies returns ClassDeclarations
with a name that is an Identifier for an array type ([LFoo$Bar;) and so the class name embedded
in it is a binary (mangled) name, and ClassDep.process does Identifier.lookup on that mangled
name, which doesn't transform back to the expected canonical "Foo. Bar" syntax, so the "seen"
table ends up with not-equal Identifiers for both "Foo$Bar" and "Foo. Bar", when there should
just be "Foo. Bar".

>             Project: River
>          Issue Type: Bug
>          Components: com_sun_jini_tool
>    Affects Versions: jtsk_2.1
>            Reporter: Fred Oliver
>            Priority: Minor
>
> Bugtraq ID [6392596|http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6392596]
> The classdep utility generates duplicate output lines when
> run under Java5.  In particular, this is seen for enum classes
> and for inner classes named on the command line.
> Consider a java source file (in src/foo/Bar.java):
> package foo;
> public class Bar {
>     private static enum Contents { RECORDS, TASKS }
>     public class Inner { }
> }
> Run:
> rm -rf classes
> mkdir classes
> javac -d classes src/foo/Bar.java
> java -cp /vob/jive/lib/tools.jar:$JAVA_HOME/lib/tools.jar \
>     com.sun.jini.tool.ClassDep \
>     -cp classes -files -in foo foo.Bar foo.Bar\$Inner
> Result:
> foo/Bar.class
> foo/Bar$Contents.class
> foo/Bar$Contents.class
> foo/Bar$Inner.class
> foo/Bar$Inner.class
> Note the two duplicate lines.
> Using jdk1.5.0_06.
