Serdar Gökay created CAMEL-26439:
------------------------------------
Summary: Generated property configurers lower-case option names
with the JVM default locale, so options with a capital I fail with "Unknown
parameters" under a Turkish locale
Key: CAMEL-26439
URL: https://issues.apache.org/jira/browse/CAMEL-26439
Project: Camel
Issue Type: Bug
Components: camel-package-maven-plugin
Affects Versions: 4.23.0
Reporter: Serdar Gökay
The velocity template {{property-configurer.vm}} in
{{camel-package-maven-plugin}} generates
{code:java}
switch (ignoreCase ? name.toLowerCase() : name) {
{code}
without a locale. {{DefaultComponent.setProperties}} binds endpoint options
with {{withIgnoreCase(true)}}, so the configurer lower-cases every option name
with the default locale. Under {{tr}} (and {{az}}) the capital {{I}} becomes
the dotless {{ı}}: {{clientId}} becomes {{clientıd}}, matches no case label,
and the configurer returns false.
The same template also lower-cases the case labels at build time ({{case
"${option.name.toLowerCase()}"}}), so the generated sources depend on the
locale of the machine that builds Camel; {{invoke-on-header.vm}} has the same
pattern. 14 calls in the velocity templates are affected.
Reproducer (Camel JBang 4.23.0, no broker needed):
{code:yaml}
- route:
from:
uri: timer:tick?repeatCount=1
steps:
- to: paho-mqtt5:demo?clientId=demo1&brokerUrl=tcp://127.0.0.1:1
{code}
* {{JAVA_TOOL_OPTIONS="-Duser.language=tr -Duser.country=TR" camel run
paho.yaml}} fails at route creation: {{ResolveEndpointFailedException ... There
are 1 parameters that couldn't be set on the endpoint}} ({{clientId}}).
* With {{-Duser.language=en -Duser.country=US}} the endpoint is created and the
route fails later, as expected, with {{Connection refused}}.
Not every option is affected: {{log:demo?showExchangeId=true}} works under
{{tr}}, presumably because the reflection fallback in
{{PropertyBindingSupport}} finds the setter after the configurer misses.
{{clientId}} lives on the paho-mqtt5 configuration object and is not found that
way.
This is the same class of problem as CAMEL-5199 ({{ObjectHelper.capitalize}},
fixed in 2.10.0), now in the generated configurers.
Proposed fix: use {{toLowerCase(Locale.ROOT)}} in the velocity templates
(runtime switch and generated case labels), regenerate the configurers, and add
a test that binds an option with a capital I under a {{tr_TR}} default locale.
