Please file a bug against the javadoc tool via the Java bug reporting page
(http://bugreport.java.com) after checking the Bug Database
(http://bugs.java.com)
for duplicates. Include error messages and the following diagnostic in
your report. Thank you.

This looks similar to
https://bugs.openjdk.java.net/browse/JDK-8151191 which is marked as
resolved in JDK 9. This issue does not reproduce in JDK 9.
To reproduce this:
$ git clone https://github.com/elastic/elasticsearch.git
<mailto:[email protected]:elastic/elasticsearch.git>
$ cd elasticsearch
$ git checkout c831442352c00f6cf840ffc3cbae64694935ce8b
$ JAVA_HOME=/path/to/jdk-10 gradle :core:javadoc
The specific revision is required because I am going to push a change
to disable Javadoc builds on JDK 10 for now so that we can get our JDK
10 builds green. The path should be a path to the root of a JDK 10
installation (e.g., the parent directory to bin).
This requires at least Gradle 4.3. The block of code that it is
tripping on is here:
https://github.com/elastic/elasticsearch/blob/c831442352c00f6cf840ffc3cbae64694935ce8b/core/src/main/java/org/elasticsearch/rest/action/cat/RestThreadPoolAction.java#L78-L98
Jason,
This looks more like a problem with your environment than a problem with
javadoc. The key message that javadoc is reporting is this:
javadoc: error - An internal exception has occurred.

I suggest you investigate why you might be having problems with the
compiled class files. This sort of error is typically due to mutually
inconsistent classes on your classpath, perhaps due to multiple
compilations.
At any rate, beyond the javadoc tool giving poor advice about filing a
bug, this is not a javadoc issue: the root of the problem lies with what
happened before you ran javadoc.
