java - Constructor of Reflections not running correctly -

i using reflections library (see info) classes within package. using following code:

public static void build() {      system.out.println("start reflection");      reflections reflections = new reflections("org.octocash.client.support.cache");      system.out.println("done constructor");      set<class<?>> dataclasses = reflections.getsubtypesof(object.class)                                 .stream().filter(c -> !c.getclass().equals(data.class))                                 .collect(collectors.toset());      data.addall(dataclasses);  } 

the problem prints "start reflection" in console, unable run constructor. if surround code try-catch block, not printing exception either.

i using uberjar reflections (not using maven), maybe has this.

what happening here? totally in dark on how debug this..

any appreciated!
