The following test failed in the JDK14 CI:

jdk/jshell/ToolTabSnippetTest.java

Here are snippets from the two failing test cases:

There are also a couple of these on stderr:

java.lang.InterruptedException

And stderr ends with this:

However, it appears that the last failure mode is a result
of the other failures.

Starting this bug as a P2 since this is a Tier1 test failure.
