Completion of error handling

[elfring]

I have looked at a few source files for your current software. I have noticed that some checks for return codes are missing.

Would you like to add more error handling for return values from functions like the following?

• malloc ⇒ launchVM
• GetModuleHandleW ⇒ getExecutableDir

The code sure could use some clean-up in terms of error handling and logging. My excuse: it's a shoddy weekend project :)

I'm happy to accept PRs in that regard, otherwise you'll have to wait for some time until i have the resources to continue working on it.

Are you interested to apply aspect-oriented software development?
How do you think about to encapsulate error detection and corresponding exception handling as a reusable aspect in your software?

I'd say keep it simple.

As @NathanSweet indicated, i think we should keep this as simple as possible. I do appreciate the benefits of AOP for bigger projects, but it would be quite an overkill for 150 LOC of Java code and 200 LOC of C.
