[Eclipse-clp-bugs] JVM crashes when executing eclipse.jar functions

[Guimarans S. D. <d.g...@hv...>]

Hello,

I am writing to report an issue I found when trying to execute Java code with calls to eclipse.jar on Mac OS X 10.12.1 (Sierra). The JDK version is 1.8.0_112-b16. The Java code executes normally if calls to the ECLiPSe engine are removed. The JVM crashes when trying to create an instance of EclipseEngineOptions, providing the following error:

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007fffd8abdb92, pid=20115, tid=0x0000000000001703

# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.
#

The problem only exists when executed in the last Mac OS X update. I run a class with about 40 students, but only 4 of them found this issue (the ones who had upgraded to the last OSX version). I upgraded one of my computers and obtained the same error. Previous versions of OSX and Windows users found no issues. I have not tested it on other OS.

A sample of the call creating the problem is attached in the following code:

import com.parctechnologies.eclipse.*;

import java.io.*;


public class EclipseConnection {

private EclipseEngine eclipse;

private Object f;
     private Object w;
     private Object cost;
     private Object costSwaps;
     private Object costPAX;
     private Object costBAX;

public EclipseConnection(String eclipseDirectory, String problemSolver, String instanceFileName) {
EclipseEngineOptions eclipseEngineOptions = new EclipseEngineOptions(new File(eclipseDirectory));

eclipseEngineOptions.setUseQueues(true);

    try {
eclipse = EmbeddedEclipse.getInstance(eclipseEngineOptions);
eclipse.compile(new File(instanceFileName));
eclipse.compile(new File(problemSolver));
} catch (EclipseException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

public void callSolver(int alpha, int beta, int gamma, int timeout) {
    CompoundTerm result;
try {
result = eclipse.rpc("solve_gap(" + alpha + "," + beta + "," + gamma + "," + timeout + ",F,W,Cost,CostSwaps,CostPAX,CostBAX)");
f = result.arg(5);
    w = result.arg(6);
cost = result.arg(7);
costSwaps = result.arg(8);
costPAX = result.arg(9);
     costBAX = result.arg(10);
} catch (EclipseException e) {
System.out.println("No feasible solution");
} catch (IOException e) {
e.printStackTrace();
}
}

public void destroy() {
    try {
((EmbeddedEclipse) eclipse).destroy();
} catch (IOException e) {
e.printStackTrace();
}
}
}

Kind regards,
Daniel
