#229: JSS method resolution failure ------------------------------------------------+--------------------------- Reporter: mevenson | Owner: nobody Type: defect | Status: new Priority: critical | Milestone: 1.1.0 Component: java | Version: Keywords: jss method-resolution abcl-contrib | ------------------------------------------------+--------------------------- [http://article.gmane.org/gmane.lisp.armedbear.devel/2402 Jonathan Bona reports]: {{{

#| 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. |# }}}
