Getting EXCEPTION_ACCESS_VIOLATION when starting tomcat under eclipse, windows 10

This has been working. Of course I've made changes, but don't know any that point in the direction the error message would indicate.

I have a Java Spring Batch application and a web app for starting any of several batch jobs. I am on eclipse photon 4.8.0, running windows 10, java 1.8, and Tomcat 7.0.59. When I start the server, the console shows normal INFO output through "Initialization processed in 2538 ms", then

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000000006d3130a2, pid=18012, tid=20820

# Problematic frame:

#
# Failed to write core dump. Minidumps are not enabled by default on client versions of Windows

and lists an error report file. In that, I see a stack dump including:

I upgraded my (minor) version of Java and configured the server to run that, but get the same error. Is anyone aware of some kind of compatibility problem or something that causes this?
