The test java/net/httpclient/BufferSizePropertyClampTest.java expect numbers to be formatted in the US/ROOT locale, with `,` as the thousands separator. The test will fail if run in a locale that has different number digits or a different thousands separator - such as e.g. the Polish language which uses a non-breaking space as separator:

```
