I was able to use SystemTap's Java probe support to do a general search for this :
probe java("/usr/lib64/eclipse//plugins/org.eclipse.equinox.launcher_1.3.0.v20131104-1241.jar").class("java.net.URLClassLoader").method("findClass(String):366") {
printf("ClassNotFoundException : %s\n", user_string($arg1))
}
...
ClassNotFoundException : com.sun.org.apache.xml.internal.serializer.XMLEntities
ClassNotFoundException : com.sun.org.apache.xml.internal.serializer.XMLEntities
ClassNotFoundException : com.sun.org.apache.xml.internal.serializer.XMLEntities_en
ClassNotFoundException : com.sun.org.apache.xml.internal.serializer.XMLEntities_en
ClassNotFoundException : com.sun.org.apache.xml.internal.serializer.XMLEntities_en_US
ClassNotFoundException : com.sun.org.apache.xml.internal.serializer.XMLEntities_en_US
Even without that I was still able to remotely debug as well without seeing the JVM
crash so I managed to get a stacktrace.
java.lang.ClassNotFoundException: com.sun.org.apache.xml.internal.serializer.XMLEntities
