> camel-bean - a comma inside ${...} in the method parameters splits the
> parameter, so OGNL calls with several arguments fail (e.g.
> ${body.substring(0, 2)})

> Key: CAMEL-25081
> URL: https://issues.apache.org/jira/browse/CAMEL-25081
> Project: Camel
> Issue Type: Bug
> Components: camel-bean
> Reporter: shashank
> Priority: Minor
> Fix For: 4.23.0
>
>
> When the method option of the Bean EIP binds parameters from the method name,
> {{MethodInfo}}
> ({{core/camel-core-processor/.../component/bean/MethodInfo.java:606-613}} on
> main) takes the text between the outer parentheses with
> {{StringHelper.betweenOuterPair}} and splits it with
> {{StringQuoteHelper.splitSafeQuote(methodParameters, ',', true, true)}}.
> {{splitSafeQuote}} only honours quotes, so it also splits at a comma inside a
> Simple expression {{$\{...\}}}, for example the arguments of an OGNL method
> call. Each half is then evaluated as its own Simple expression, which is not
> closed, and every exchange fails.
> h3. Reproduction
> Main (dbdd4b381), bean {{echo(String s)}} returns {{[s]}} and {{two(String a,
> String b)}} returns {{[a|b]}}:
> {noformat}
> bean(MyBean.class, "echo(${body.substring(0, 3)})") body abcdef
> -> SimpleParserException: expected symbol functionEnd but was eol: missing
> } to close the function
> expected [abc]
> bean(MyBean.class, "two(${body}, ${header.v.replace('a', 'b')})") body X,
> header v = aaa
> -> SimpleParserException: expected symbol functionEnd but was eol: missing
> } to close the function
> expected [X|bbb]
> controls: echo(${body}), two(${body}, ${header.v}), echo('a,b') work
> {noformat}
> It fails loudly (not silently) and there is a workaround: compute the value
> into a header first and pass {{$\{header.x\}}}. A jqwik property over
> {{$\{body.substring(i, j)\}}} fails for every input.
> This is the same class of problem that CAMEL-24967 fixed for the arguments of
> Simple functions (a comma or parenthesis inside a nested {{$\{...\}}} or a
> quoted argument split the arguments). The bean parameter parsing was not part
> of that change. It was found while working on CAMEL-25033 (PR #26908), which
> changes how the parameter values are evaluated but not how the parameter text
> is split.
> h3. Proposed fix
> Split the parameter text with a depth-aware splitter that ignores the
> separator inside quotes, inside {{$\{...\}}} and inside parentheses, as
> CAMEL-24967 did for Simple functions. A Lean model of the splitter shows that
> for every input in which no comma sits inside brackets, the depth-aware
> splitter gives exactly the result of {{splitSafeQuote}} today (for example
> {{$\{body\}, $\{header.foo\}}}, {{'a,b', 5}}, {{*, true}}), so only the
> inputs that fail today change.
> Tests: {{BeanParameterValueTest}} (or similar) with
> {{echo($\{body.substring(0, 3)\})}} and {{two($\{body\},
> $\{header.v.replace('a', 'b')\})}}; the existing parameter binding tests must
> keep passing.
> Duplicate check (2026-09-28): JIRA {{component = camel-bean AND text ~ OGNL
> AND text ~ parameter}} and {{text ~ "method name" AND text ~ comma}} return
> only CAMEL-24967 (Simple functions). No open PR.
