Illegal State Exception is an Unchecked exception   It indicate that method has been invoked at wrong time    example   Thread t   new Thread    t start          t start      output   Runtime Excpetion  IllegalThreadStateException   We cant start the Thread again  it will throw IllegalStateException

Usually  IllegalStateException is used to indicate that  a method has been invoked at an illegal or inappropriate time   However  this doesn t look like a particularly typical use of it   The code you ve linked to shows that it can be thrown within that code at line 259 - but only after dumping a SQLException to standard output   We can t tell what s wrong just from that exception - and better code would have used the original SQLException as a  cause  exception  or just let the original exception propagate up the stack  - but you should be able to see more details on standard output  Look at that information  and you should be able to see what caused the exception  and fix it
