Adding OutputListener to Output Window instances (OutputWriter)

[nedpals]

Hi! I am currently developing a plugin for a research project I'm making at the moment which involves listening for incoming error messages from the terminal. My idea was that since Java projects (ant/maven/gradle) run on a dedicated output window, the stderr portion will be passively piped into my program for analysis.

However I find it very difficult to achieve this one (in combination with scattered information and "dead" links which I am frustrated at) to the point that I did the work myself to locate the relevant source code only to find this.

netbeans/platform/core.output2/src/org/netbeans/core/output2/ErrWriter.java

Line 186 in 94a19f0

wrapped.print(s, null, false, null, null, OutputKind.ERR, addLineSep);

Turns out I can attach an OutputListener explicitly if my module do the call (eg. io.getErr().print("test", outputListener)) but not on this one. Is there anyway I can attach an OutputListener to an ErrWriter? Is this monkey-patchable. Hoping for an immediate response. Thanks!
