---------------------------------------
Summary: IllegalArgumentException on weaving
Key: ARIES-1755
URL: https://issues.apache.org/jira/browse/ARIES-1755
Project: Aries
Issue Type: Bug
Components: SPI Fly
Affects Versions: spifly-1.0.8
Reporter: James Phillpotts
On weaving a jar that contains a utility loading class like this (this example
is an enum, but the same happens if it's a class, anonymous inner class, etc.):
{code:java}
public enum Loader {
LOADER;
public <S> S load(Class<S> type) {
Iterator<S> services = ServiceLoader.load(type).iterator();
return services.hasNext() ? services.next() : null;
}
}
{code}
The weaving throws this exception:
{noformat}

This happens regardless of whether static or dynamic weaving is used.
I'll attach a sample project.
