             Summary: UtilHttp file upload fails for files > 2GB with ViewHandlerException: Cannot read more than 2,147,483,639 into a byte array
                 Key: OFBIZ-13473
                 URL: https://issues.apache.org/jira/browse/OFBIZ-13473
             Project: OFBiz
          Issue Type: Improvement
          Components: framework
            Reporter: Chandan Khandelwal


Uploading files larger than 2GB in OFBiz fails with the following exception: org.apache.ofbiz.webapp.view.ViewHandlerException: Cannot read more than 2,147,483,639 into a byte array

Root Cause: In UtilHttp.java (line 298), multiPartMap.put(fieldName, ByteBuffer.wrap(item.get())) calls item.get() on Commons FileUpload DiskFileItem for every uploaded file.

Java byte arrays are capped at Integer.MAX_VALUE minus 8 bytes overhead, which equals 2,147,483,639 bytes (~2.00 GB). Uploading files larger than this limit throws an IllegalArgumentException, which OFBiz catches and wraps into ViewHandlerException.
