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.

> Reporter: David Georg Reichelt
> Assignee: Gary D. Gregory
> Priority: Critical
> Time Spent: 0.5h
> Remaining Estimate: 0h

> Currently, if I try to write a sufficiently big to a stream, IOUtils.write
> fails:
> {code:java}
> java.lang.NegativeArraySizeException: -1283060862
> at java.base/java.lang.StringCoding.encodeUTF8(StringCoding.java:904)
> at java.base/java.lang.StringCoding.encode(StringCoding.java:449)
> at java.base/java.lang.String.getBytes(String.java:964)
> at org.apache.commons.io.IOUtils.write(IOUtils.java:3251)
> at org.apache.commons.io.FileUtils.writeStringToFile(FileUtils.java:3541)
> at
> org.apache.commons.io.FileUtils.writeStringToFile(FileUtils.java:3524){code}
> The reason for this is that getBytes does not support Strings with this size.
> This should be fixed.
