GF3.1.2_b20: Exception while trying to weave class

Hi,

I have come across a strange error when deploying our application on the
latest 3.1.2 Glassfish. When deploying, there are the usual log lines "class
XYZ actually got transformed" and so on. However, on one class I get a
ClassNotFoundException:

Weaver encountered an exception while trying to weave class
xyz/OrderBookBean. The exception was: java.lang.RuntimeException:
java.lang.ClassNotFoundException: xyz.OrderBookPositionBean not found by
org.eclipse.persistence.asm [117]
The named classes are in the same package and so I do not know why it cannot
be found. The classes have a OneToMany relationship with each other.

I have discovered the following EclipseLink bugs which describe the
behaviour:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=363238

https://bugs.eclipse.org/bugs/show_bug.cgi?id=365385

 

Did anyone else encounter this and knows how to fix this? The strange part is
that if I change a little bit in the code (replaced a for-each-loop with a
normal for-loop) the weaving succeeds. But I would also like to understand
this. ;)

What are the performance implications of having weaving disabled?

 

Any help appreciated.

Thanks,
Chris.
