Mark Roberts commented on BCEL-279:
-----------------------------------
The signature processing in BCEL has not been updated to support generic types.
I have been trying to add some support (see
https://issues.apache.org/jira/browse/BCEL-285) but the code really needs a
complete rewrite. It should probably be modified to use
sun.reflect.generics.parser.
> Utility.methodSignature* throw ClassFormatException when converting binary
> names with generics.

> Key: BCEL-279
> URL: https://issues.apache.org/jira/browse/BCEL-279
> Project: Commons BCEL
> Issue Type: Bug
> Components: Parser
> Affects Versions: 6.0
> Reporter: Dongsun Kim
> Fix For: 6.1
>
>
> When I try the following, Utility class throws ClassFormatException:
> {code}
> String sig =
> "<T:Ljava/lang/Object;>(Lcom/google/common/io/ByteProcessor<TT;>;)TT;"
> Utility.methodSignatureArgumentTypes(sig, false)
> {code}
> The above signature actually exists in com.google.common.io.ByteSource in
> Google Guava.
> Utility.methodSignatureReturnType does not throw any exception but its return
> value does not look valid.
> When I try this:
> {code}
> String sig =
> "<T:Ljava/lang/Object;>(Lcom/google/common/io/ByteProcessor<TT;>;)TT;"
> Utility.methodSignaturerReturnType(sig, false)
> {code}
> expected: java.lang.Object
> actual: T
> It seems that org.apache.bcel.generic.Type.java also has the same issue.
