Automatic test hangs in javamixed suite. 

Prepare JNI projects: 
- Launch NetBeans Dev 201609050002 on Ubuntu 16.04
- Create Java project 
- Add simple JNI code. For example: 
package javaapplication2; 

public class JavaApplication2 { 

public static void main(String[] args) { 
System.loadLibrary("CppJNILibrary_2"); 
foo(); 
} 
public static native void foo(); 
} 

- Build Java project 
- Call context menu on Java file in Project tab 
- Select Tools|Mixed Development|Generate JNI Library Project 
- Press Finish button in New Project wizard 
- Add "puts("Hi!");" into JavaApplication2.c 
- Build native library 
- Lainch Java project 
==> I see "Hi" message in Output tab

Scenario: 
- Set line breakpoint in "foo();" line in JavaApplication2.java 
- Push "Debug Project" button in tool bar 
- Push "Step Into" button in tool bar 
==> after small delay Dbx stopped on "puts("Hi!");" line 
- Open Sessions tab 
- Call context menu on "javaapplication2.JavaApplication2" row 
- Select "Make Current" 
==> IDE hangs
