Unable to run using safeexec

[laalamrajesh]

(1) Run this command (from java_jail):
./java/bin/java -cp .:cp:cp/javax.json-1.0.jar:java/lib/tools.jar traceprinter.InMemory < cp/traceprinter/test-input.txt

(2) Try with safeexec (from java_jail):
/path/to/safeexec --chroot_dir . --exec_dir / --share_newnet --nproc 50 --mem 3000000 --nfile 30 --env_vars CLASSPATH=/cp/:/cp/javax.json-1.0.jar:/java/lib/tools.jar --exec /java/bin/java traceprinter.InMemory < cp/traceprinter/test-input.txt

(1) working fine but when i am running safexec i am getting below error. unable to debug it.

error 2 (No such file or directory): execve error
