Description chhh 2013-12-04 17:54:51 UTC 
this bug relating to output window has been closed a couple of times, but I see the same broken behavior in 7.4 now.

System.out.print("HOHOHO\rHAHAHA\n");

output:

run:
HOHOHO
HAHAHA
HOHOHO
HAHAHA
BUILD SUCCESSFUL (total time: 0 seconds)

i meant that line twice:
    System.out.print("HOHOHO\rHAHAHA\n");
    System.out.print("HOHOHO\rHAHAHA\n");

Possible fix

Patch that adds support for CR characters.

The patch seems to work quite fine, but I'll have to test it a little.

I'm afraid that some users might rely on the current behavior, and the patch could cause some trouble, although no modern system should use CR as line separator.

Have you considered ANSI sequence \u001B[2K instead of CR? It works similarly, should work on most systems, and is already supported in NetBeans:

System.out.println("HOHOHO\u001B[2KHAHAHA");

Thank you for reporting.
