> Rebind failure: Cannot coerce or set value
> ------------------------------------------
>
> Key: BROOKLYN-193
> URL: https://issues.apache.org/jira/browse/BROOKLYN-193
> Project: Brooklyn
> Issue Type: Bug
> Affects Versions: 0.8.0, 0.9.0, 1.0.0
> Reporter: Valentin Aitken
> Labels: starter
>
> *Use case*
> If you submit a blueprint with a value of invalid type it is accepted.
> This causes writing invalid data to persistence and which leads to a failure
> on rebind.
> *Steps to reproduce:*
> # Submit a blueprint with a Map value where string value is expected.
> Enter a {color:red}wrong BP{color}
> {code}
> location: aws-centos6
> services:
> - type: org.apache.brooklyn.entity.webapp.tomcat.TomcatServer
> java.sysprops:
> test: false
> provisioning.properties:
> minRam: 4
> minHdd: 100
> {code}
> Instead of {color:green}a correct one{color}
> {code}
> location: aws-centos6
> services:
> - type: org.apache.brooklyn.entity.webapp.tomcat.TomcatServer
> java.sysprops:
> test: false
> provisioning.properties:
> minRam: 4
> minHdd: 100
> {code}
> # Let's say that by mistake you nest provisioning.properties into
> java.sysprops (java.sysprops is Map<String, String>)
> # The blueprint is accepted and deployed successfully.
> # Restart Apache Brooklyn
> # A startup error occurs
> {code:none}
> java.lang.IllegalArgumentException: Cannot coerce or set'

> java.lang.IllegalArgumentException: Cannot coerce or set {minRam=4,
> minHdd=100} to
> java.sysprops.provisioning.properties[ConfigKey:java.lang.String]

> ~[classes/:na]
> Caused by: org.apache.brooklyn.util.core.flags.ClassCoercionException: Cannot
> coerce type class com.google.common.collect.Maps$TransformedEntriesMap to
> java.lang.String ({minRam=4, minHdd=100}): no adapter known
> at
> org.apache.brooklyn.util.core.flags.TypeCoercions.coerce(TypeCoercions.java:272)
> ~[classes/:na]
> {code}
> *Short-term workaround*
> The persisted state for the relevant entities can be modified to remove the
> incorrect configuration value.
> *The steps to do this are:*
> # stop Apache Brooklyn.
> # backup your existing persisted state.
> # replace the relevant files with those attached.
> # start Apache Brooklyn.
> *Long-term solution*
> We are looking at improvements to Apache Brooklyn: to allow rebind, even when
> there are configuration errors like this (e.g. where the invalid
> configuration value is dropped).
