Subject Re: ArrayIndexOutOfBoundsException in ServletInputStream.readLine
Date Thu, 16 Feb 2017 08:36:32 GMT
Hi Violeta,

Thank you for your reponse.
I found the following setting in my server.xml. Does this answer your question?

    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443"
maxThreads="700" packetSize="65536" useBodyEncodingForURI="true" />
