[SasinduDilshara]

Description

Following code gets a HeapOutOfMemory error while compiling.

service /jsonpath on new http:Listener(9090) {
    resource function get test() returns error|json {
        return jp:readJson(store, `$.store.book[*].price`);
    }
}

json store = <large json with 100000+ fields>

ballerina: Oh no, something really went wrong. Bad. Sad.

We appreciate it if you can report the code that broke Ballerina in
https://github.com/ballerina-platform/ballerina-lang/issues with the
log you get below and your sample code.

We thank you for helping make us better.
