Nathan Bubna commented on VELOCITY-736:
---------------------------------------

David, that is almost certainly because commons-fileupload 1.2 was compiled with JDK \
1.5.  The structure of the testcase code matches that of the commons-fileupload code \
in question.   I would imagine you could fix your problem by recompiling fileupload \
with JDK 1.6, though i haven't tried that.

Also, note the latest on VELOCITY-745, for a possible demonstration of why the \
allowed scope is "public methods declared in public classes".  It appears that \
Method.invoke seems to care about the protection of the class in which the method was \
declared, at least in JDK 1.5, which is the target JDK for Velocity 1.7.


> Introspection regression from 1.5 to 1.6.2
> ------------------------------------------
> 
> Key: VELOCITY-736
> URL: https://issues.apache.org/jira/browse/VELOCITY-736
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 1.6.2
> Environment: Sun JDK 1.5
> Reporter: David Esposito
> Attachments: Velocity736TestCase.java
> 
> 
> When upgrading from Velcocity 1.5 to 1.6.2, the following snippet of code changed \
> behavior.  In Velocity 1.5, the output was:
> The file upload exceeded 100
> In Velocity 1.6.2, the output is:
> The file upload exceeded $ex.permittedSize
> There is nothing in the velocity log file to help me identify why it's not \
> resolving 'permittedSize' to the correct bean method. Here is a test program to \
> replicate the problem. The context variable in question is the Commons FileUpload \
> exception class documented here: \
> http://commons.apache.org/fileupload/apidocs/org/apache/commons/fileupload/FileUploadBase.SizeLimitExceededException.html
>  I am using commons-fileupload-1.2.jar
> import java.io.StringWriter;
> import org.apache.commons.fileupload.FileUploadBase;
> import org.apache.velocity.VelocityContext;
> import org.apache.velocity.app.VelocityEngine;
> import org.apache.velocity.context.Context;
> public class Main {
> public static void main(String[] args) throws Exception{
> VelocityEngine e = new VelocityEngine();
> 		String testTemplate = "The file upload exceeded $ex.permittedSize";
> 		StringWriter out = new StringWriter();
> 		Context ctx = new VelocityContext();
> 		FileUploadBase.FileSizeLimitExceededException ex = new \
> FileUploadBase.FileSizeLimitExceededException("too big!", 50, 100);  \
> ctx.put("ex",ex);  e.evaluate(ctx, out, "Tester", testTemplate);
> 		System.out.println(out.toString());
> }
> }
