Just to follow up on this with a little more info, I've put together a small example that demonstrates the issue I'm seeing.
Consider this class "Outer", which includes an inner class "Inner":
public class Outer { public static Inner getAnInner(){ return new Inner(); } static class Inner{ public Inner(){ } public void innerm(){ System.out.println("called innerm"); } } }
In Java, I can instantiate Inner and call its public methods, as in the following:
public class TestMain { public static void main(String[] args){ Outer.Inner myinner = new Outer.Inner(); myinner.innerm(); } }
However, in ABCL 1.0.1:
CL-USER(1): (jnew "Outer$Inner") #<THREAD "interpreter" {7FB5438D}>: Debugger invoked on condition of type JAVA-EXCEPTION Java exception 'java.lang.IllegalAccessException: Class org.armedbear.lisp.Java$pf_jnew can not access a member of class Outer$Inner with modifiers "public"'.
I can still get an instance to play with:
CL-USER(3): (jstatic "getAnInner" "Outer") #<Outer$Inner Outer$Inner@67df02c9 {62300F65}>
… but I can't call its public methods:
CL-USER(6): (jcall "innerm" (jstatic "getAnInner" "Outer")) #<THREAD "interpreter" {7FB5438D}>: Debugger invoked on condition of type JAVA-EXCEPTION Java exception 'java.lang.IllegalAccessException: Class org.armedbear.lisp.Java can not access a member of class Outer$Inner with modifiers "public"'.
… unless I use JSS and with-constant-signature
CL-USER(7): (require :abcl-contrib) CL-USER(8): (require :jss) CL-USER(9): (jss::ensure-compatibility) CL-USER(10): (with-constant-signature ((innerm "innerm")) (innerm (jstatic "getAnInner" "Outer")) ) called innerm NIL
Any help getting to the bottom of this would be greatly appreciated.
Regards, Jonathan

Hey guys,
Have any of you had a chance to look into this? This is a showstopper for me using the latest ABCL as I have basic infrastructure code that is failing.
Would much appreciate someone having a look.
Thanks, Alan

Hello,
We found this issue while working with LSW. It seems to be a bug in how public methods are found for inner classes. The last line of code below results in an exception rather than finding and running the size() method:
;;;---------------- (require :abcl-contrib) (require :jss) (jss::ensure-compatibility) (setq headers (#"getHeaderFields" (#"openConnection" (jss::new 'java.net.url "http://google.com"))))
; a java.util.Collections$UnmodifiableRandomAccessList (setq ural (#"get" headers (second (jss::set-to-list (#"keySet" headers)))))
;finds: #<method public int java.util.Collections$UnmodifiableCollection.size()> (find "size" (#"getMethods" (#"getClass" ural) ) :test 'string-equal :key #"getName")
; Java exception 'java.lang.NoSuchMethodException: No applicable method named size found in java.lang.Object or java.util.Collections$UnmodifiableRandomAccessList'. (#"size" ural) ;;;----------------
I chased this into org.armedbear.lisp.Java, where findMethod is returning null.
