We are getting at nightly test failure on Linux.

Using a command line like this:

$JAVA_HOME/bin/java -server -DHANGINGJAVA7642 -XX:CompileThreshold=100
-XX:+PrintCompilation -XX:CompileOnly=java -XX:-Inline
-XX:CICompilerCount=1 -XX:+UseJumpTables -jar
$JAVA_HOME/demo/jfc/SwingSet2/SwingSet2.jar -runs=3 -delay=10 -lf=10

on role.sfbay,

starting with your 9/12 JumpTables putback, we get an assertion
failure in codeBuffer.hpp:
