--------------------------------

             Summary: 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


When I try the following, Utility class throws ClassFormatException:

String sig = "<T:Ljava/lang/Object;>(Lcom/google/common/io/ByteProcessor<TT;>;)TT;"
Utility.methodSignatureArgumentTypes(sig, false)

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:

String sig = "<T:Ljava/lang/Object;>(Lcom/google/common/io/ByteProcessor<TT;>;)TT;"
Utility.methodSignaturerReturnType(sig, false)

expected: java.lang.Object
actual: T

It seems that org.apache.bcel.generic.Type.java also has the same issue.

Dongsun.
