Title: Re: [aspectj-users]java.lang.StackOverflowError atorg.aspectj.weaver.ReferenceType.isAssignableFrom(ReferenceType.java:292)
Unless you’re talking about a really strange VM with which I am unfamiliar, the VM allocates the entire stack allocation size each time a thread is started.  No additional allocations take place for the stack itself; i.e., it will not grow.

I guess I am left wondering why type maps are being stored in a WeakHashMap instead of a strong one.

Just my 2 cents,
Kevin

Interesting. I wouldn’t have expected that, but perhaps the VM ran out of heap memory in allocating a stack frame and because it ran out of memory it reported stack overflow.

Hi Ron!

Thanks a lot for the reply!

The strack trace is of 1024 function calls... it seems a bit too deep for me (I didn't paste the full stack trace in the email).

I tried your suggestion and it didn't work. However it made me thing and I added -Xms128m -Xmx256m (since I'm passing those parameters when running in a lab where I don't get the error) and it solved the problem.....

I don't exactly see why having less available memory would result in a StackOverflow instead of an OutOfMemory error.....

Hi Santiago,
 
You might try running your test with a larger stack size, since this doesn’t look like an infinite loop. Try adding a VM argument –Xss2048k to your junit runner to do this. This value is four times the default, so you probably can run with less, but doing this should test whether this fixes the problem (as I suspect it will). Java programs with deep stacks sometimes need a larger value here. And running from Eclipse has different stack depths, so the discrepancy isn’t too surprising.

Hi,

I'm using AspectJ 1.5.3 using LTW and writing *most* of my aspects code style. I get the following stack trace when running a test case from ant:

[junit] java.lang.StackOverflowError
    [junit]     at java.util.WeakHashMap.expungeStaleEntries(WeakHashMap.java:269)
    [junit]     at java.util.WeakHashMap.getTable(WeakHashMap.java:297)
    [junit]     at java.util.WeakHashMap.get(WeakHashMap.java:341)
    [junit]     at org.aspectj.weaver.World$TypeMap.get(World.java:967)
    [junit]     at org.aspectj.weaver.World.resolve(World.java:250)
    [junit]     at org.aspectj.weaver.World.resolve(World.java:191)
    [junit]     at org.aspectj.weaver.UnresolvedType.resolve(UnresolvedType.java:662)
    [junit]     at org.aspectj.weaver.ReferenceType.getRawType(ReferenceType.java:550)
    [junit]     at org.aspectj.weaver.ReferenceType.isAssignableFrom(ReferenceType.java:292)
    [junit]     at org.aspectj.weaver.ReferenceType.isAssignableFrom(ReferenceType.java:276)
    [junit]     at org.aspectj.weaver.ReferenceType.isAssignableFrom(ReferenceType.java:292)
.....

Strangely, I don't get the error if running my test cases from inside Eclipse. If I'm not wrong, eclipse uses it's own compiler while when running from ant I'm compiling with Sun's compiler (1.5.0_09).

I don't really know what else to do... I suspect the issue is while handling generics, but not much else. I'm willing to provide any additional information to help me diagnose the problem.

I'm attaching the generated ajcore files.

thanks a lot,

saludos
