The following command never finishes when executed from Java: (example using in Groovy)
println "lxc exec example-test -- echo Hi".execute().text
What I have tested:
Runtime.getRuntime().exec()also halts when using
- Any other command like:
lxc info example-test, etc. has not problem
"echo Hi".execute().textreturns ‘Hi’ as expected.
- Running the same command from bash returns immediately.
- Interestingly, running it inside perl, the code won’t return unless I press
Checking the Java native source code (java.io), it seems that
BufferedInputStream.readBytes its waiting for a termination character that is never returned. However I can see in the buffer the value: “Hi\n” (followed by zeros) just before waiting forever.
Any suggestions on how to debug or make it work?
