Recently I discussed that Biojava could be changed to Java version 1.5 without breaking compatibility since the novel tool Retroweaver allows to run Java 1.5 programs on older JREs.
I started to use enums in my program and did not encounter any problems related to retroweaving. However there is one nasty problem which shows up only at runtime: In Java 1.5 but not in 1.4 exists the method StringBuffer#insert(int, CharSequence) In Java 1.4 and 1.5 exists the method. StringBuffer#insert(int, Object) After compiling with the javac version 1.5 and retroweaving one gets a NoSuchMethodError runtime error because #insert(int, CharSequence) does not exist in the 1.4 runtime library. The workaround is simple - just casting StringBuffer to Object so that the method #insert(int, Object) is taken instead of #insert(int, CharSequence). I already told the author of retroweaver. Otherwise retroweaver works very well. _______________________________________________ Biojava-l mailing list - Biojava-l@biojava.org http://biojava.org/mailman/listinfo/biojava-l
