Chapter 4. Known issues
Migration Toolkit for Applications (MTA) version 8.0.0 is affected by the following newly identified and previously known issues. A known issue is listed in all future release notes until resolved, at which point it is published as a fixed issue.
Application analysis with MTA CLI might fail with the "invalid header line" error
An application analysis by using the Migration Toolkit for Applications (MTA) command-line interface (CLI) might fail with the following error message:
level=error msg="initialize failed" error="context canceled" provider=java error="invalid header line "An error has occurred. See the log file"
level=error msg="initialize failed" error="context canceled" provider=java
error="invalid header line "An error has occurred. See the log file"To work around this problem, clean up metadata and cache:
-
Clear the
.metadatasubdirectory under the directory from which you ran themta-cli analyzecommand. - Clear the Maven cache.

MTA analysis result does not change if you add or remove a custom rule
When you use Developer Lightspeed for MTA, the analysis results do not change if you include or remove a custom rule but do not restart the analyzer process.
To work around this problem, restart the analyzer process by clicking the Start/Stop button after making a configuration change.

ANNOTATION location rules do not match on FQNs
The ANNOTATION search location does not properly use Fully Qualified Names (FQNs) to match annotations. This leads to incorrect matches and false positives in analysis issues. For example, a rule that searches for annotations using the javax.enterprise.inject.Produces pattern might incorrectly match the occurrences of the javax.ws.rs.Produces annotation in the source code.
No known workaround exists.

Developer Lightspeed for MTA database throws a connection error
The Solution Server throws a connection error when concurrent connections increase in a short span of time. To work around this problem, enter the following command to allow the Developer Lightspeed for MTA database to expire idle connections:
oc -n openshift-mta exec deploy/kai-db – psql -U postgres -d postgres -c "ALTER ROLE kai SET idle_session_timeout = '1min'; ALTER ROLE kai SET idle_in_transaction_session_timeout = '1min';"
oc -n openshift-mta exec deploy/kai-db – psql -U postgres -d postgres -c "ALTER ROLE kai SET idle_session_timeout = '1min'; ALTER ROLE kai SET idle_in_transaction_session_timeout = '1min';"(MTA-6204)
