Hi All,
What the need to support jdk 1.4 in the OOXML branch is? What about making JDK
1.5 a minimum requirement since POI 3.5?
Currently only ooxml code uses JDK 1.5 features. The OLE2 stuff is compatible with jdk 1.4. That means we can't use
enums, generics and other 1.5 features in HSSF and other OLE2 projects.
It's 2008. J2SE 1.4.2 will reach its End of Service Life in October 2008:
http://java.sun.com/j2se/1.4.2/download.html
I think we can start using 1.5 features throughout the ooxml branch and,
probably, in trunk.
If 1.4 compatibility is required, there are tools to convert 1.5 code into 1.4
compatible.
The most well-known is Retroweaver:
http://retroweaver.sourceforge.net/
It operates by transforming Java class files compiled by a 1.5 compiler into class files which can be run on an older
virtual machine. Interestingly, other Apache projects already use Retroweaver, for example FOP.
What do people think?
