pendingTransactionFlowable non deterministic issue

[adkr]

pendingTransactionFlowable removes '0' in filterId

pendingTransactionFlowable doesn't work randomly due to different filterId used between RPC calls.

Steps To Reproduce

Issue is non deterministic.

Expected behavior

FilterId registered for the purpose of pending transactions monitoring and used in getFilterChanges should be the same.

Actual behavior

FilterId from filter registration and monitoring calls (getFilterChanges) differs.

Environment

• Web3j version: 4.12.2
• Java: 21
• Operating System: Windows

Additional context

[adkr]

Unfortunately, same issue again... It happens in the context of the web3j.pendingTransactionFlowable method call. Please note that removed "0" in getFilterChanges comparing to a filter id returned at the beginning.

About behavior... Since my first post web3j "just" started working fine after multiple re-runs. Never happened again until today.
