  JDK 8 SR4 FP 10 changed the return of
  java.util.zip.ZipFile.getEntry(String) to include ending / for
  a directory.  This might cause a directory to not be found.
  

Problem conclusion

• The WebContainer code was modified to accommodate the change
  in the Java JDK.
  
  The fix for this APAR is currently targeted for inclusion in
  fixpacks 8.5.5.13, 9.0.0.6 and WebSphere Liberty  17.0.0.4.
