RemoveTryCatchFailBlocks triggers a Java Template parse failure

[kthoms]

What version of OpenRewrite are you using?

I am using rewrite-maven-plugin:5.42.0 /

• OpenRewrite v8.45.1
• Maven plugin 5.42.0
• rewrite-testing-frameworks v3.2.0

How are you running OpenRewrite?

I am using the Maven plugin, and my project is a multi module project.

https://github.com/operaton/operaton/tree/v1.0.0-beta-3

Execution is

# build the project once before without testing
./mvnw verify -DskipTests -Dskip.frontend.build=true

# perform recipe on the 'engine' module
mvn -U org.openrewrite.maven:rewrite-maven-plugin:run -Drewrite.recipeArtifactCoordinates=org.openrewrite.recipe:rewrite-testing-frameworks:RELEASE -Drewrite.activeRecipes=org.openrewrite.java.testing.assertj.JUnitToAssertj -Drewrite.exportDatatables=true -f engine

What is the smallest, simplest way to reproduce the problem?

https://github.com/operaton/operaton/blob/v1.0.0-beta-3/engine/src/test/java/org/operaton/bpm/engine/test/bpmn/mail/EmailSendTaskTest.java

What is the full stack trace of any errors you encountered?

I haven't been able to reproduce when running RemoveTryCatchFailBlocks, but what stands out is that the only try ... catch in this Java file is this line: https://github.com/operaton/operaton/blob/v1.0.0-beta-3/engine/src/test/java/org/operaton/bpm/engine/test/bpmn/mail/EmailSendTaskTest.java#L190 And the only thing special there I can see is the | syntax for catching two exception classes (catch (MessagingException | IOException e)).

What the exception here says is that what couldn't be parsed was the Java template code, not the source file itself. So this is either a bug in the recipe or possibly the template engine itself.
