Re: Moving to Java 1.5, retroweaving for 1.4 (was: svn commit: r805561 [1/2]....)
There we go again. ;-) I can understand the wishes and cravings of the developers (feeling them myself), but as I've said before: such a decision should be made with the user community in the back, i.e. there should be another user survey to gather current data. Just because Sun EOLs a Java version doesn't mean that everyone can suddenly just do the switch. So why don't those who want this change so badly do that little survey so we have the data on an informed decision? As for retroweaving: I've just set the necessary values in my build-local.properties and tried to compile the latest FOP Trunk with Java 1.5.

Re: Moving to Java 1.5, retroweaving for 1.4 (was: svn commit: r805561 [1/2]....)
Thanks for the retroweaver report. I believe I removed all methods which are not Java 1.4 compliant. I tried to do a compilation in Java 1.4, but I failed with an UnsupportedClassVersionError, which I am not going to investigate now. So I could not test this myself.
