Public bug reported:

This issue affects Ubuntu 16.04.3, specifically the openjdk-9-jre-
headless:amd64 package, version 9~b114-0ubuntu1.

jexec, in the openjdk-9-jre-headless:amd64 package, is a tool used for
launching jars by calling java.  However, running jexec against a jar
results in:

can't locate java: No such file or directory

Currently, /usr/lib/jvm/java-9-openjdk-amd64/lib/jexec appears to want
to access /usr/lib/jvm/java-9-openjdk-amd64/jre/lib/jexec (based on
running "strings jexec"). However, there is no /usr/lib/jvm/java-9
-openjdk-amd64/jre directory. Running strace on jexec shows this:

lstat("/usr/lib/jvm/java-9-openjdk-amd64", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/usr/lib/jvm/java-9-openjdk-amd64/jre", 0x7fffcafd9bc0) = -1 ENOENT (No such file or directory)
dup(2)                                  = 3
fcntl(3, F_GETFL)                       = 0x8002 (flags O_RDWR|O_LARGEFILE)
brk(NULL)                               = 0x95a000
brk(0x97b000)                           = 0x97b000
fstat(3, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 2), ...}) = 0
write(3, "can't locate java: No such file "..., 45can't locate java: No such file or directory
) = 45
close(3)                                = 0
exit_group(1)                           = ?
+++ exited with 1 +++

Creating the directory /usr/lib/jvm/java-9-openjdk-amd64/jre/lib/, and
placing in it a link to /usr/lib/jvm/java-9-openjdk-amd64/lib/jexec,
allows jexec to function properly.
