[Biojava-l] Error running in Linux

[Ng Peck Leng]

Hi,

I encounter the following errors when running a simple program in Linux, but 
it works perfectly well on Windows:

Exception in thread "main" java.lang.VerifyError: verification failed at PC 68 
in org.biojava.bio.symbol.AlphabetManager:getAlphabetIndex
((Lorg.biojava.bio.symbol.FiniteAlphabet;)
Lorg.biojava.bio.symbol.AlphabetIndex;):incompatible return type
   at 0x40268e17: java.lang.Throwable.Throwable(java.lang.String) 
(/usr/lib/./libgcj.so.3)
   at 0x4025bc8e: java.lang.Error.Error(java.lang.String) 
(/usr/lib/./libgcj.so.3)
...
...
...
These are the files that I'm currently using:
biojava-1.30-jdk14.jar
bytecode-0.91.jar
jakarta-regexp.jar
xerces.jar

Is there any incompatibility issues here? Thanks!

regards,
Peck
