FlexNet Manager for Engineering Applications Admin startup fails with NumberFormatException: “For input string: ‘\U’

Title

During startup of the FlexNet Manager for Engineering Applications Admin service, the following error may appear in the server logs:

ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool – 125) MSC000001: Failed to start service jboss.deployment.subunit."flexnet.ear"."flexnet.war".undertow-deployment:

org.jboss.msc.service.StartException in service jboss.deployment.subunit."flexnet.ear"."flexnet.war".undertow-deployment:

java.lang.NumberFormatException: For input string: "\U"

When this occurs, the FlexNet Manager for Engineering Applications Admin service appears to start, but the web UI fails to load.

Root cause

This error is triggered by corrupted license data. The order of increment lines in the license file is critical, and manually concatenating license fragments can introduce formatting errors.

Solution

Generate a clean, consolidated license file

Access the Product and License Center by logging into the Flexera Community and going to Product Access > Product and License Center.
Generate a new license file using the Consolidate option to create a full license bundle. For detailed steps, see Steps to generate the FNMEA license file.
Do not manually merge or edit individual license fragments.

Replace the corrupted license file

Backup and remove the existing license file from:

<FNMEA Admin install directory>/config/license

Copy the newly consolidated license file into the same location.

Rebuild and restart

Rebuild the site directory using the command:

flexnet site make

Start the Admin service.

Verify resolution

Confirm in the logs that the NumberFormatException no longer appears.
Confirm that the FlexNet Manager for Engineering Applications web UI loads successfully.
