#1 Failure to start jar on Mac OS X

[Anonymous]

Hi

I tried to launch the B3V2993 JAR on a Mac OSX 10.3.9 (Panther) with Java version 1.4.2_12. However,

java -jar B3V2993.jar

yields this result:

Exception in thread "main" java.lang.UnsupportedClassVersionError: gnu/b3/B3 (Unsupported major.minor version 49.0)
