[Bug-glpk] Java Runtime Env. Error

[Yang Ji]

Dear Glpk Developer,

 

I use Glpk for Windows (4.40) and program 
with Java SKD 6 Update 18.

 

Sometimes it works well, sometime not, I have got the 
correct result as follow or

 

the error report, just randomly.

 

I hope, there is some here can help me. Thanks a lot in 
advance.

 

best regards,

 

Yang
