This section contains miscellaneous information about YajHFC not included in the FAQ or other documentation.

If you did not find the answer you were looking for here, please also see the FAQ and the yajhfc-user mailing list archive.

Versions

Generally any Java 5, 6 and 7 should work.
Due to additional features available, using Java 6 or heigher is recommended (also Java 5 support may be dropped some time in the future).

yajhfc-console only supports Java 6 or heigher.

Implementations

YajHFC is usually tested against the JRE from Oracle for Windows (32 and 64 bit; newest version available at the time of release) and against OpenJDK for Linux (Debian; 64-bit). For Mac OS X, both the Apple and Oracle versions of Java are supported.

Other implementations (such as GCJ) may or may not work. If you use something other than the "official" Oracle JRE or OpenJDK and some feature does not work (correctly), please first try if it works if you use one of those implementations before reporting a bug (if possible).
Anyway, if you have made positive or negative experiences with other Java implementations, please let me know.

Especially with Windows 10 and Oracle Java 1.8 you might notice that the main window is suddenly almost completely white or black and you need to restart YajHFC to get it working again.

Usually this looks like this:
White window

This seems to be a bug in Java with the Windows native "look and feel".
To work around this issue, set Options → General → Look&Feel to "Metal" or "Nimbus".
