RE: BCEL with JDK 1.1.8

Hi Enver,
 
 
Is it possible that I could get some older BCEL binary from apache which would not have your jdk 1.2 dependencies? Also, if not, then could I get the older source code which was not jdk 1.2 specific, and then I could compile it on my jdk 1.1.8.
 
Could you please let me know? Thanks a lot.
 
Regards,
Manjari.

	Hi, 

	Seems the 5.1 package was not compiled with a 1.1 JDK. 
	Hm, I doubt that the BCEL package will still compile 
	under 1.1 since I even checked in some classes of the 
	verifier GUI that depend on Swing. I believe I also 
	used collection classes, so the whole verifier should 
	depend on 1.2, not only the GUI. 

	However, one could possibly compile all the packages 
	except the *.verifier.* using a 1.1 compiler. 

	The error message you get is most probably because 
	your runtime environment JVM expects *.class files 
	of version 45.3 (compiled with JRE-1.1 in mind), but 
	nowadays recent compilers emit 48.0 version *.class 
	files that can no longer be interpreted by ancient 
	JREs. For them, one needs to recompile the source. 

	I wonder if we should still go for 1.1 compatibility 
	by the way... 

	Greetings, 
	Enver
