> -------- Original Message --------
> *Change Request ID*: 7104161
> *Synopsis*: test/sun/tools/jinfo/Basic.sh fails on Ubuntu
>
>
> === *Description* ============================================================
> This test fails in the TL nightly testing on Linux when run on systems that have non-child ptrace disabled (which seems to be all recent releases of Ubuntu).
>
> Attached is a sample results file. It's the same issue as 7050524 but that bug is closed as it was used to add release notes to jdk7.
>
> The new bug asks that the test be modified so that the test is modified to only use jinfo -flag (this is the only option to jinfo that uses the attach mechanism rather than SA), or the test be modified to check /proc/sys/kernel/yama/ptrace_scope before it uses options that require SA. If the test is fixed in a timely manner then we will add to the jdk/ProblemList.txt file so that it is excluded by the Makefile. Changing all test machines isn't really an approach here as the tests should pass on newly installed systems.
