        Transfer(web3j, transactionManager).sendFunds(credentials.address, BigDecimal.valueOf(100), Convert.Unit.ETHER).send()

}

Expected behavior

Test should end up with a clear exception (there is not enough ether to pay the gas fee)

Actual behavior

Test failed with IllegalArgumentException.

Environment

• Web3j version 4.8.8
• Java 11.0.13
• Operating System Windows 10

Additional Context

There are logs when using web3j 4.8.4

11:41:28.016 [pool-1-thread-1] WARN org.hyperledger.besu.ethereum.mainnet.MainnetTransactionProcessor - Invalid transaction: transaction up-front cost 100000000000000021000 exceeds transaction sender account balance 10000000000000000000

And the test end up with timeout

org.web3j.protocol.exceptions.TransactionException: Transaction receipt was not generated after 30 seconds for transaction: 0x3ba70c783a4e130fd2f7eaf06682c7f05715928abbbe00d59be2d2aeb3cc1586

I firstly encountered the IllegalArgumentException when deploying a contract. After the investgation I guess it also caused by no enough ether to pay. It may be a web3j-unit related issue (not enough ether in provided account or wrong gas price). I need some suggestions.

[azige]

Here are things I tested. It seems web3j-unit provided account has only 10 ether.
Contracts compiled by solc 0.8.10.

• web3j 4.8.8
  • transfer 100 ether: IllegalArgumentException
  • transfer 1 ether: success and correct
  • deploy a contract: IllegalArgumentException
• web3j 4.8.4
  • transfer 100 ether: TransactionException （timeout)
  • transfer 1 ether: success and correct
  • deploy a contract: success
  • call contact functions: success and correct
