NetBeans 8.2 introduces NPE at org.net beans.modules.j2me.common.ant.CopyLibletsTask. execute(CopyLibletsTask.java:93)

Good morning,

I have a bigger ME project (with 2430 Java files) which compiles well with
NetBeans 8.0.2 and 8.1, but fails to run with NetBeans 8.2.

Here is the output with "--debug" added to Maven and Ant set to "Debug"
level too:

I have tried to look deeper, but couldn't find anything yet.

I post the above error in the hope, that someone well versed with NetBeans
source code will spot the error.

Is maybe Roman's change http://hg.netbeans.org/main-silver/rev/812b25952dee
the culprit?
