Method resolveJavaMethod

src/bsh/Reflect.java:422–469

The full blown resolver method. All other method invocation methods delegate to this. The method may be static or dynamic unless staticOnly is set (in which case object may be null). If staticOnly is set then only static methods will be located. This method performs caching (caches disco
