Seeing `casecase` pop up when running IfElseIfElseToSwitch

Seeing the case gets put in Space whitespace during template apply

I can see that in a unit test the Java21Parser is used, which results in correct lst elements returned from the JavaTemplate.

After changing the runtime dependency to an implementation one, I changed the code:

JavaTemplate.builder(switchBody.toString())
                    .javaParser(Java21Parser.builder())
                    .build()
                    .apply(cursor, if_.getCoordinates().replace(), arguments).withPrefix(if_.getPrefix());

forcing the usage of the same Java21Parser, but this throws

java.lang.IllegalAccessError: superclass access check failed: class org.openrewrite.java.isolated.ReloadableJava21Parser$ByteArrayCapableJavacFileManager (in unnamed module @0x2eb7e207) cannot access class com.sun.tools.javac.file.JavacFileManager (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.file to unnamed module @0x2eb7e207
