             Summary: System.out.flush() doesn't flush all data to output window
                 Key: NETBEANS-2099
                 URL: https://issues.apache.org/jira/browse/NETBEANS-2099
             Project: NetBeans
          Issue Type: Improvement
          Components: platform - Output Window
    Affects Versions: 9.0, 10.0
         Environment: Product Version: Apache NetBeans IDE 10.0 (Build incubator-netbeans-release-380-on-20181217)
Java: 11.0.1; OpenJDK 64-Bit Server VM 11.0.1+13
Runtime: OpenJDK Runtime Environment 11.0.1+13
System: Windows 8.1 version 6.3 running on amd64; Cp1252; en_US (nb)
            Reporter: Stephan van Hulst


Consider the following application:
{code:java}
public static void main(String... args) {
    System.out.print("Hello\nWorld!");
    System.out.flush();
}{code}
After executing the first statement, the following line is printed to the output window:
{code}
Hello
{code}
After executing the second statement, I expect the remainder of the printed string to appear in the output window:
{code}
Hello
World!
{code}
The flush does not appear to have any effect, however.

When executing this program from the Windows command line, it works as expected.

Since the documentation of {{OutputStream.flush()}} mentions that the behavior of flush is operating system dependent, this is not really a bug, but it would be really nice if it flushed to the output window the same way it flushes to the command line window.
