Description:
Zowe SYSPRINT (from spool) contains log entries that are split and mixed together. See example:

Impact:
When logs are mixed together, it is very difficult to analyze them. In some cases, like when two messages of the same kind are mixed together (stack traces, certificate dumps, http dumps) it is impossible to distinguish which lines belongs together.

Expectated output:
Logs are not mixed together, multiline log entries are printed as a whole.

Steps to reproduce:
This issue does not seem to be related to any particular setup. In our case, we run APIML integration tests with debug enabled.

Notes:
It looks like a bug of log manager which operates on a per-line basis.

This is the unified log from the launchers point-of-view, and has all streams merged. There may be per-component (e.g. APIML) logs also captured and stored in a component-specific place, and the APIML config doc should say where. There is a proposal and prototype for allowing launcher logs to have per-component subdivision, using SYSOUT DDName's, but it has never gone into to roadmap or quarterly plan.
