When a JVM starts crashing like that, it is a sign that something has broken the JVM's execution model.

Does your application include any native code? Does it use any 3rd-party libraries with native code components? If neither is true, then the chances are that this is a bug in the Apple port of the JVM. It could be a JIT compiler bug, or a bug in some JVM native code library.

What can you do about a bug like that?

Not a lot.

<ul>
<li>Reduce your application by progressively chopping out bits until you have a small testcase that exhibits the problem.</li>
<li>Based on the testcase, see if there's some empirical way to avoid the problem.</li>
<li>Submit a bug report to Apple with the testcase.</li>
</ul>

I just came across this situation and it turned out to be related to a piece of code that was serializing a JSON object with a cyclic reference to itself. I removed the cycle and the error went away. I suspect this is related to a memory overflow error that is now handled differently by newer JVMs on Mac OSX. In this case, I was running Mac OSX 10.7. 

For completeness the errors I was receiving were:

<pre><code>Invalid access of stack red zone 0x10e586d30 rip=0x10daabba6
Bus error: 10
</code></pre>

And:

<pre><code>Invalid memory access of location 0x10b655890 rip=0x10a8baba6

I've been working on a Java project for year. My code had been working fine for months. A few days ago I upgraded the Java SDK to the newest version 1.6.0_26 on my Mac (Snow Leopard 10.6.8). After the upgrade, something very weird happens. When I run some of the classes, I get this error:

Invalid memory access of location 0x202 rip=0x202

But, if I run them with -Xint (interpreted) they work, slow but work fine. I get that problem in classes where I use bitwise operators (bitboards for the game Othello). I can't put any code here because I don't get an error, exception or something similar. I just get that annoying message. 

Is it normal that the code doesn't run without -Xint but it works with it? What should I do?

Thanks in advance

我从事Java项目已经有几年了。我的代码几个月来一直运行得很好。几天前，我在我的Mac上把Java SDK升级到了最新版本的1.6.0_26 (雪豹10.6.8)。升级后，会发生一些非常奇怪的事情。当我运行一些类时，我得到这个错误：位置0x202 rip=0x202的内存访问无效但是，如果我用-Xint (解释型)运行...
