JVM crash during (de)serialization

[Richard Chrenko]

While saving (or reading) a complex object from the filesystem using
Serialization I am getting intermittent JVM crashes with the following
error message. The "locked" LinkedList looks suspicious, but I don't know
what this is trying to tell me. Does anyone know what it means or a clever
way to go about isolating the error?

------------------------------------------------------------

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC=0x6A17EF6
Function=[Unknown.]
Library=(N/A)

NOTE: We are unable to locate the function name symbol for the error
just occurred. Please refer to release documentation for possible
reason and solutions.
