I used Retroweaver on a Java 1.5 JAR file (targeting
1.4), and here is what happened at runtime :
java.lang.NoSuchMethodError:
java.lang.Double.valueOf(D)Ljava/lang/Double;
A quick look at the javadoc reveals that this method
appears in Java 1.5.
Logged In: YES
user_id=1635915
The version of Retroweaver used there was Retroweaver 2.0Beta2 (build 275).
Logged In: YES
user_id=1635915
To be more specific,
this code is compiled in 1.5 :
public Double getMinXValue()
{
return 6.0;
}
then weaved to 1.4. Once decompiled we have :
public Double getMinXValue()
{
return Double.valueOf(6D);
}
which results in the above exception.

I tried to reproduce the problem but the call is translated
correctly:
public java.lang.Double getMinXValue();
Signature: ()Ljava/lang/Double;
Code:
0: ldc2_w #1; //double 6.0d
3: invokestatic #23; //Method
net/sourceforge/retroweaver/runtime/java/l
ang/Double_.valueOf:(D)Ljava/lang/Double;
6: areturn
Could you provide a small example to reproduce the problem?
Thanks,
Xavier

Maybe that I extracted from the code the wrong line but I thought it was this one responsible for the
problem.
This exactly how I get this exception (and several others I posted) :
- The goal is to have Apache Trinidad demo application working with Tomcat 5.0 and JDK 1.4 (my exact
version 1.4.2_07).
- Download http://people.apache.org/maven-snapshot-repository/org/apache/myfaces/trinidad/trinidad-
demo/incubator-m1-SNAPSHOT/trinidad-demo-incubator-m1-SNAPSHOT.war into <Tomcat_Dir>/webapps
- Restart then stop Tomcat so that the war file is expanded
- Use Retroweaver 2.0Beta2 (build 275) on <Tomcat_Dir>/webapps/trinidad-demo-incubator-m1-SNAPSHOT/WEB-
INF/lib/trinidad-api-incubator-m1-SNAPSHOT.jar and <Tomcat_Dir>/webapps/trinidad-demo-incubator-m1-
SNAPSHOT/WEB-INF/lib/trinidad-impl-incubator-m1-SNAPSHOT.jar (for those 2 jar files, I used the
Retroweaver ANT Task targeting 1.4)
- Add retroweaver-rt-2.0Beta2.jar and backport-util-concurrent.jar in <Tomcat_Dir>/webapps/trinidad-
demo-incubator-m1-SNAPSHOT/WEB-INF/lib/
- Finally, Retroweaver 2.0Beta2 (build 275) has to be used on <Tomcat_Dir>/webapps/trinidad-demo-
incubator-m1-SNAPSHOT/WEB-INF/classes/
- Start Tomcat and test the application using a web browser on http://<host>:<port>/trinidad-demo-
incubator-m1-SNAPSHOT/
Here are all the problems I encountered while navigating this demo application :
Component Guide > chart

Then, once source code altered to avoid this error :

Of course the demo works perfectly on Tomcat 5.5 and Java 1.5.
I know you just asked me a "small example to reproduce the problem", and what I gave here was the whole
process...
But I already tried to extract the interesting lines from the source file, and it looks like I did it
wrong because you couldn't reproduce the problem with it. And it might be useful because it illustrates
a way to reproduce several problems I reported.
But If you prefer the "small example" anyway, let me know, I will try to produce it.

Sorry for the long delay... Another user found a similar problem and the issue seems to be that the retroweaver-rt-<version>.jar was not in the class path during the weaving process so the valueOf substitution wasn't picked up.
Could you try to redo the weaving, making sure that the rt jar file is in the classpath?
Thanks,
Xavier

Hi,
We used a workaround for this part of the code (In the end it appeared that we had no use for it).
Everything is now working as we wanted so I will not be able to modify it for the moment.
So you can consider the problem as closed if this solution works and if nobody complains about it again
Thanks for your time.
