Try catch causes docker conatiner crash with multiple sub shells. about bash-oo-framework

It looks like that in this case we also have to add import util/log:

++(exception.sh:33): command_not_found_handle(): [[ ls /root2 = \(\ \s\e\t\ \-*\;\ \t\r\u\e* ]]
++(exception.sh:38): command_not_found_handle(): Exception::CustomCommandHandler ls /root2
++(exception.sh:17): Exception::CustomCommandHandler(): return 1
++(exception.sh:38): command_not_found_handle(): true
++(exception.sh:40): command_not_found_handle(): local script=/opt/workflow/bin/wf
++(exception.sh:41): command_not_found_handle(): local lineNo=13
++(exception.sh:42): command_not_found_handle(): local 'undefinedObject=ls /root2'
++(exception.sh:43): command_not_found_handle(): local type=/root2
++(exception.sh:45): command_not_found_handle(): [[ ls /root2 == \(*\) ]]
++(exception.sh:50): command_not_found_handle(): [[ -z ls /root2 ]]
++(exception.sh:55): command_not_found_handle(): [[ 1 -gt 0 ]]
++(exception.sh:57): command_not_found_handle(): subject=level3
++(exception.sh:57): command_not_found_handle(): Log 'inside Try No.: 1'
++(exception.sh:30): command_not_found_handle(): local 'IFS=

++(exception.sh:33): command_not_found_handle(): [[ Log inside Try No.: 1 = \(\ \s\e\t\ \-*\;\ \t\r\u\e* ]]

Same issue here with multiple sub-shells spawning unto death.
GNU bash, version 4.3.46(1)-release (x86_64-pc-linux-gnu)

Thanks for the report (and sorry for the late answer), unfortunately I don't have resources (time) right now to tackle this. If any of you figure this out, please file a PR with the fix or recommendation.

Could you make a minimal reproduction Dockerfile repository?

[remipichon]

Here is a Dockerfile to reproduce the issue

• Dockerfile

FROM ubuntu

RUN apt-get update && apt-get install -y git

WORKDIR /root
RUN git clone https://github.com/niieani/bash-oo-framework.git

COPY script.sh script.sh
RUN chmod +x script.sh

CMD ["./script.sh"]

# build
# docker build -t test_try_catch .
# run
# docker run test_try_catch

• script.sh

#!/usr/bin/env bash
source "$( cd "${BASH_SOURCE[0]%/*}" && pwd )/bash-oo-framework/lib/oo-bootstrap.sh"

import util/tryCatch
import util/exception # needed only for Exception::PrintException

# it does work when log are imported
# import util/log

try {
   echo "try"
   exit 1

} catch {
    echo "catch"
    echo "Error in $__EXCEPTION_SOURCE__ at line: $__EXCEPTION_LINE__!"
}

• build with docker build -t test_try_catch .
• test with docker run test_try_catch
• it will exhaust your cpu so docker kill might help
• uncomment line 8 of script.sh to have it working

Hope this helps, thanks !
