I would highly recommend upgrading the JVM on one of those servers to 1.7.latest to see if everything still works. If things go well, upgrade all of them. Then deploy the 1.8.latest to one of them. Tomcat shouldn't have any compatibility issues with Java 8, but you will definitely want to test everything in your application of course. - -chris > ________________________________ From: Christopher Schultz > <ch...@christopherschultz.net> Sent: Friday, January 27, 2017 > 1:52:47 AM To: Tomcat Users List Subject: Re: Apache Tomcat/7.0.39 > crashed with fatal error > > Satish, > > On 1/26/17 2:28 PM, Satish Chhatpar 02 wrote: >> we are using Apache Tomcat/7.0.39 for our java application. > > I highly recommend an upgrade for both Tomcat and Java.
