exception in jte plugin: LeafPsiElement cannot be cast to class CompositeElement

I’m not sure how to reproduce this, and it doesn’t cause me any obvious trouble, just reporting some stuff my IDE showed me.

java.lang.ClassCastException: class com.intellij.psi.impl.source.tree.LeafPsiElement cannot be cast to class com.intellij.psi.impl.source.tree.CompositeElement (com.intellij.psi.impl.source.tree.LeafPsiElement and com.intellij.psi.impl.source.tree.CompositeElement are in unnamed module of loader com.intellij.util.lang.UrlClassLoader @6a2bcfcb)

The jte-intellij plugin 1.2.0 was approved by JetBrains and is available with this fix.
