[Bug 57638] IllegalArgumentException in AjpNioProcessor when packetSize > 8192

What version the stacktrace is from?

> at java.nio.Buffer.limit(Buffer.java:275)

The line matches Java 8u31 sources.
The IAE is triggered by the following check:

[[[
public final Buffer limit(int newLimit) {
   if ((newLimit > capacity) || (newLimit < 0))
            throw new IllegalArgumentException();
]]]

> org.apache.coyote.ajp.AjpNioProcessor.readSocket(AjpNioProcessor.java:179)

The above does not match Tomcat 7 sources. By method name I guess that is line
356.

[[[
    private int readSocket(byte[] buf, int pos, int n, boolean block)
            throws IOException {
        int nRead = 0;
        ByteBuffer readBuffer =
                socketWrapper.getSocket().getBufHandler().getReadBuffer();
        readBuffer.clear();
        readBuffer.limit(n);
]]]

Apparently it tries to read n bytes from the Socket read buffer at once. The
buffer is smaller that that thus the IAE.
