Question

Error while executing below code,

Caused by: java.lang.IllegalAccessError: tried to access class com.google.common.collect.AbstractTable from class

Answer 1

Interesting, i replaced method references with Lambda expression and it worked.

    ImmutableTable.copyOf(itemList.parallelStream()
                    .map(item ->
                            ProcessorInstanceProvider.get()
                            .buildImmutableTable(item))
                    .collect(() -> HashBasedTable.create(),
                            (a, b) -> a.putAll(b),
                            (a, b) -> a.putAll(b))
                    );
