NetBeans 6.5.1 & Mac OS X Java Update 4

[John B. Matthews]

On Mac OS X 10.5.7, after Java Update 4, NetBeans IDE 6.5.1 (Build
200903060201) fails when adding new files, typically:

java.lang.reflect.UndeclaredThrowableException
java.lang.NoClassDefFoundError: javax/script/ScriptEngine

A workaround is to copy script-api.jar to an extension folder:

$ mkdir -p ~/Library/Java/Extensions
$ cp /Applications/NetBeans/NetBeans\ 6.5.1.app/Contents/\
Resources/NetBeans/platform9/modules/ext/script-api.jar \
Library/Java/Extensions/.

Other Mac OS X ext directories are discussed here:
