Microsoft Windows [Version 6.1.7600]
A DESCRIPTION OF THE PROBLEM :
The SequenceInputStream uses recursion to read additional data when there is more space to fill in the provided buffer.
In my scenario, I have an Enumeration<FileInputStream> of about 16k files that are all zero bytes of length. I then use the SequenceInputStream#read(byte[], int, int) method to read bytes from the streams.
Because after each zero-byte read the next stream is retrieved from the Enumeration and then a recursive call to the same read(byte[], int, int) method is done, I get a SOE.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No SOE.
ACTUAL -
