We know absolutely nothing about your program. How could we possibility guess why it might behave differently on the Mac. This is what debuggers are for. Run it under debug control and if it handles, pause the process and see what it's doing at that point in time.

If it's a core dump of the JVM, I'd try to get a new version of the JVM.

Hi

Use a debugger to find out where it does wrong, or a tool such as Visual VM to inspect the dumps.

If you can't do this, there is always printf debugging to print out relevant information just before and (by omission) just after the hang. You have a Linux/Windows version to use as an oracle. Concentrate on system sensitivities such as memory, environment, file name spelling, line endings.

According to error log, the eclipse is crashed because of "libswt-cocoa-4530.jnilib". Do you know what should I do?
I have an "OS X EI captain", I downloaded eclipse mars from epsilon site (I want to use epsilon 1.3). Does higher version of eclipse solve my problem? Which another "eclipse modeling" can I download? I see https://www.eclipse.org/modeling/downloads/ but I cannot find the suitable version of it for my OS, also I see other platforms link.

You should install Oxygen, the modeling package if you want that. You should be able to install all other things you want into that.

And to be explicit, you should get it from https://www.eclipse.org/downloads/

Hi

Epsilon is available from https://www.eclipse.org/epsilon/download/ It provides a convenience download for MACOS, but I doubt that there is anything in Epsilon that is more than accidentally platform sensitive. Just install http://www.eclipse.org/downloads/download.php?file=/epsilon/updates/site.zip on a respectable modeling installation.

Eclipse User

your java command points to the stub binary which uses current version configured

$ ls -la /usr/bin/java
lrwxr-xr-x 1 root wheel 74 Feb 5 2015 /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
all you need is to update your JAVA_HOME(I've added that to my ~/.profile):

export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)
