Description Jeonghoon Lee 2015-02-13 04:38:39 UTC
Class org.apache.coyote.Request has bytesRead variable's return type is int.

When file upload (grater than 2 GB), it returns negative value.

Return type should be change to long.

This bug affected all version of tomcat 6, 7, 8, 9.



private int bytesRead=0;

public int getBytesRead() {
   return bytesRead;


private long bytesRead=0;

public long getBytesRead() {
   return bytesRead;
