isa() does not work to check Java interface implementation about octave-slf4o

[apjanke]

Hmm. Maybe I'm wrong about Octave not getting interface implementation right:

>> str = javaObject('java.lang.String', 'foobar')
str =
<Java object: java.lang.String>

>> isa(str, 'java.lang.String')
ans = 1
>> isa(str, 'java.lang.Object')
ans = 1
>> isa(str, 'java.lang.CharSequence')
ans = 1
>>

Need to look into my own code more deeply. Maybe the interface structure has changed with the newer version of SLF4M or log4j.

Aha. Looks like it doesn't properly detect interfaces inherited from a superclass. I'm not crazy.

debug> jLogger
jLogger =
<Java object: org.slf4j.impl.Log4jLoggerAdapter>

debug> klass = jLogger.getClass;
debug> klass.getName
ans = org.slf4j.impl.Log4jLoggerAdapter
debug> superklass1 = klass.getSuperclass;
debug> superklass1.getName
ans = org.slf4j.helpers.MarkerIgnoringBase
debug> superklass2 = superklass1.getSuperclass;
debug> superklass2.getName
ans = org.slf4j.helpers.NamedLoggerBase
debug> ifcs2 = superklass2.getInterfaces;
debug> ifcs2(1).getName
ans = org.slf4j.Logger
debug> isa(jLogger, 'org.slf4j.Logger')
ans = 0
debug>

Bummer. This doesn't work either.

>> wantKlass = javaMethod('forName', 'java.lang.Class', 'org.slf4j.Logger')

error: [java] java.lang.ClassNotFoundException: org.slf4j.Logger
