Bruno P. Kinoshita updated BCEL-289:
Description:
BCEL crashes when parsing the constructor of an inner class whose parameters
are annotated. For instance, when parsing the jar obtained from the following
classes:
{code:java}
public @interface A {}
public @interface B {}
public class Test {
public class Inner {
public Inner(@A Object a, @B Object b) {}
}
}
{code}
In particular:
{code:java}
ClassParser cp = new ClassParser(args[0]);
ClassGen cg = new ClassGen(cp.parse());
MethodGen mg = new MethodGen(cg.getMethodAt(0),
cg.getClassName(), cg.getConstantPool());
mg.getAnnotationsOnParameter(0);
{code}
(where args\[0\] points to Test$Inner.class)
you get
