David Georg Reichelt commented on IO-764: ----------------------------------------- Yes, it works if you start it with -Xmx8g (and I testet with OpenJDK 11 and 8). The question is whether this would be suitable for regular testing in CI (than, surefire needs -Xmx8g), or whether I should disable the test by default. > IOUtils.write() throws OutOfMemoryError/NegativeArraySizeException while > writing big strings > -------------------------------------------------------------------------------------------- > > Key: IO-764 > URL: https://issues.apache.org/jira/browse/IO-764 > Project: Commons IO > Issue Type: Bug > Affects Versions: 2.11.0 > Reporter: David Georg Reichelt > Assignee: Gary D.
