If there are multiple JDKs installed on a Windows machine an application may not be able to use the correct Lucida font that shipped with that JDK. This is most obvious when using the Devanagari (Hindi) glyphs in the font since they only appeared in 1.4. This means that if you have 1.3 and 1.4 installed on the machine then you may not be able to access the Hindi glyphs.

I encountered this problem with an application running under JDK1.4 that used the Devanagari glyphs in the Lucida font being run on a machine with JDK1.3, JDK1.3.1, and JDK1.4 installed on it in that ordering. Until I removed 1.3 and 1.3.1 I was unable to access the Devanagari glyphs likely because the JDK was using the older Lucida fonts.
