Jenkins Amazon EC2 plugin version 1628.v6d7b_fc58b_a_1d "can't save instance config" bug can be reproduced by -
- As noted in "Environment" section above, ensure in Cloud configuration for launching an EC2 node: ensure "Instance Metadata Supported?" is checked (enabled)
- Launch a node
- Edit that node's config, change any setting except "Instance Metadata Supported?", and click "Save"
- Angry Jenkins shows up
- Go back and uncheck "Instance Metadata Supported?" and click "Save" - it will work this time
The logs show a large stack trace, of which this is the pertinent part:
Caused: java.lang.IllegalArgumentException: Failed to convert the metadataSupported parameter of the constructor public hudson.plugins.ec2.EC2OndemandSlave
Effect of the bug: You are unable to change the node configuration after launch, and keep "Instance Metadata Supported?" sub-options enabled at the same time
