Description Kirill Frolov

2002-01-06 02:57:39 EST

I got a smallplugin that parses all the members of all known classes.
I got a StackOberflowException when I parse some particular class (I found out 
that it was sun.misc.ProxyGenerator$ProxyMethod class on which I got this)

Actually my method 
org.eclipse.jdt.javadoc.internal.index.impl.Indexer.indexType is called for 
every source and binary types found in all the package fragments of the 
particular Java project.
My method in turn calls IType.getFields, IType.getMethods and IType.getSubTypes
(). Here is the stacktrace.

Actually there are some exceptions (like the first one) when I have no 
particular idea why they arise.

The stacktrace is peovided below (partially of course :-)) )

and the same exception once again

Comment 1 Philipe Mulet

Stack overflow does not mean circularity, it simply means that the execution 
stack is too deep (too many nested method calls).

Some of the operation performed by the JavaModel, like hierarchy creations can 
be somewhat expensive, and should be used reasonabily.

As for the Java model exceptions you are seing, those are described in the API, 
e.g.:

public interface IParent {
/**
 * Returns the immediate children of this element.
 * Unless otherwise specified by the implementing element,
 * the children are in no particular order.
 *
 * @exception JavaModelException if this element does not exist or if an
 *      exception occurs while accessing its corresponding resource
 */
IJavaElement[] getChildren() throws JavaModelException;

So in brief, this bug does not necessarily indicate anything wrong in our 
implementation, but probably indicates your plugin is too intensive on CPU (you 
might want to play with the runtime stack size - setting on the VM side), or 
change your algorithm to be more lightweight.

Is it ok to close ? Or do you have more specific information available that 
would clearly expose a bug in our code ?

Well, actually, bug reproduces even when java.exe runtime parameters include -
Xss2M (2 megabyte of stack space per thread). I do think that this situation is 
abnormal.

Besides it seems that the pair of classe BinaryType and OverflowingLRUCache 
form some form of circular algorithm without an exit. Here is the circle element

I cannot find any reason for this functions to enter the infinite iterative 
loop thus overflowing the stack. There should be no case for this functions to 
call themselves infinely. And this IS an error.

Sounds nasty, need to investigate.

What are the classfiles you are trying to open ? The content of the ouput 
location of a project ? These would pretend not to exist (since not on the 
classpath). But this doesn't explain why flushing the cache would cause an 
infinite loop.

Comment 5 Kirill Frolov

First, the classfile is
sun.misc.ProxyGenerator$ProxyMethod

Second, the project's name is "Eclipse" and it has the default output location 
<Eclipse>/Workspace/Eclipse/bin

Actually the problem may arise because of the VERY special nature of the class. 
And when you simply try to load this very class and find out its methods and 
attributes it works fine. The exception is only occures when you load class by 
class all Project classes and all JDK classes. I can supply the exact piece of 
code that reproduces the problem.

This would be very nice of you. A reproduceable scenario is exactly what we 
need.

Comment 7 Philipe Mulet

Waiting for a test case. Please reopen when it becomes available

Comment 8 Philipe Mulet

Waiting for information

Comment 9 Philipe Mulet

Closing as never reproduced in a long time.
