Subject [jira] [Updated] (BCEL-279) Utility.methodSignature* throw ClassFormatException when converting binary names with generics.
Date Sat, 20 Aug 2016 13:47:21 GMT

     [ https://issues.apache.org/jira/browse/BCEL-279?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Benedikt Ritter updated BCEL-279:
---------------------------------
    Description: 
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.
