Summary: ArrayIndexOutOfBoundsException when marshalling a large element
Type: Bug
Status: Closed
Priority: Blocker
Resolution: FIXED
Original Estimate: Unknown
Time Spent: Unknown
Remaining: Unknown
Project: JiBX
Components:
core
Fix Fors:
1.0-beta3b
Versions:
1.0-beta3a
Assignee: Dennis Sosnoski
Reporter: Gareth Farrington

Environment: JDK 1.4.2_04
WinXP Pro
Description:
An exception is thrown when marshalling an element that contains more than 4k of data.
If the element contains less than 4k of data the marshalling compleates normally.
Some good sample output with 850 bytes of data is included at the end. I havn't tested
unmarshalling larg elements yet.
