Java -target and -source

Not a Processing issue, but it's useful info if you're developing libraries. Depending on the version of Java that you're using, specifying -target 1.1 when compiling libraries for distribution may not be enough to get a 1.1 compatible class file. You may also need to indicate source compatibility. It seems that -source 1.3 is the most recent Java release that is capable of creating 1.1 targeted .class files. All that said, here's a typical compile string for me:

Code:
javac -source 1.3 -target 1.1 -classpath %P5_HOME%\lib\core.jar -d . package/dirs/*.java


Is this worth adding to the compatibility section in the Library HowTo.txt?

right, the part about -target is... but not about -source. People building libraries under Java 1.4 and higher are likely to need to specify -source as well.
