GCJ verification error

Mon Apr 2 09:45:00 GMT 2007

I want to compile a java program with gcj 4.1.2,
that compiled fine under gcj 4.0.2, but with 
with 4.1.2 i get the error message:
error: verification failed at PC=14: String, int, or
float constant expected
for the line:
if (Thread.interrupted())
If i comment out the line mentioned above, i get the
same error at:
synchronized (Prism.class)
Does anyone know a simple solution for that? Will an
update to a newer gcj/gcc version will be the cure?
Thank you in advance
