system.reflection - understanding Invocation Target Exception wrapping in Java -


m method , want invoke on specific instance through reflection. following code show how did invokation:

try {     m.invoke(classinstance);                 } catch (oopassertionerror e) {  } catch (exception e) {     system.out(e.getcause().getclass().getname()); }

now instance suppose throw following class when invoke specific method tried invoke earlier, m in previous code:

public class oopassertionerror extends assertionerror { }

i thought program catch oopassertionerror catch exception instead . , prints following line : "package.oopassertionerror".

why happening ?

invocationtargetexception wraps method's exceptions, written in javadoc.

see what cause java.lang.reflect.invocationtargetexception? more details.

good luck in reflections! ;)
