The failure for https://ci.chromium.org/ui/p/flutter/builders/prod/Linux%20module_test/17882 is:

And for the other one:

[2024-02-23 16:16:02.795434] [STDOUT] stderr: 	at java.base/sun.nio.ch.Net.connect0(Native Method)

[2024-02-23 16:16:02.795566] [STDOUT] stderr: 	at java.base/sun.nio.ch.Net.connect(Net.java:568)

These both look network related to me. We should catch both these error messages in the tool gradle_errors handling.

@christopherfujino There is only one flake of this test in the past >700 runs. Should we close this issue?
