Make Freedomotic compatible with Java 11 about freedomotic

[aumarbello]

Hello, would like to pick this issue up.

Which version should it be tested agaist? 9 or 10?

[dmitraver]

I had problems building the project having java 10. Can run it again and post error messages here.

@aumarbello java 10
@dmitraver yes, thanks

@mcicolella What would fixing this issue entail, just checking if it runs on Java 10 or also making changes to ensure it runs smoothly on Java 10?

[mcicolella]

@aumarbello for now we need to know if there are some problems with newer versions.

[aumarbello]

Okay, would run on Java 9 and 10 and report back any issues I experience.

@aumarbello thanks for your help.

Currently Java 11 is the default version.
Freedomotic is not compatible: the code doesn't compile on JDK 11 and the binary based on Java 8 doesn't run on 11.
We need to fix it ASAP.

The main problem is related to this code block
URLClassLoader classLoader = (URLClassLoader) ClassLoader.getSystemClassLoader(); Class<?> clazz = classLoader.loadClass(pojo.getHierarchy()); //eg: com.freedomotic.things.impl.ElectricDevice EnvObjectLogic logic = null; try { logic = (EnvObjectLogic) clazz.newInstance(); logic.setPojo(pojo); injector.injectMembers(logic); } catch (InstantiationException ex) { LOG.error(Freedomotic.getStackTraceInfo(ex)); } catch (IllegalAccessException ex) { LOG.error(Freedomotic.getStackTraceInfo(ex)); }

ClassLoader can't be casted to URLClassLoader in Java 11.

I will try to make it compatible with Java 11.
