---------------------------
Summary: ClassFormatException: [Invalid signature: `TT;'] when
using Utility.signatureToString
Key: BCEL-178
URL: https://issues.apache.org/jira/browse/BCEL-178
Project: Commons BCEL
Issue Type: Bug
Reporter: Will N
A very similar issue to [Bug
48279|https://issues.apache.org/bugzilla/show_bug.cgi?id=48279] -
{{Utility.signatureToString(...)}} can fail with this exception:
{noformat}
Caused by: org.apache.bcel.classfile.ClassFormatException: Invalid signature:
`TT;'
at org.apache.bcel.classfile.Utility.signatureToString(Utility.java:855)
at org.apache.bcel.classfile.Utility.signatureToString(Utility.java:765)
at
org.apache.bcel.classfile.LocalVariable.toString(LocalVariable.java:236)
at
org.apache.bcel.classfile.LocalVariableTypeTable.toString(LocalVariableTypeTable.java:122)
...
{noformat}
This is failing for my code which has a variable typed as {{T}} like this:
{code:java}
<T> Envelope buildRequest(Class<T> contentClass) {
Envelope result = buildEnvelope(); // some holder type
T body = Utils.newInstance(contentClass); // generic method returning an
instance of contentClass
// ... more work ...
return result;
}
{code}
I've fixed this locally following the pattern used in [Bug
48279|https://issues.apache.org/bugzilla/show_bug.cgi?id=48279]'s fix (see
r897699), essentially adding the {{'T'}} option next to {{'L'}} in the
{{Switch}} statement (see attached patch)
