Solve the problem that ireport cannot be opened after jdk is upgraded to 1.8

Some reasons for iReport-5.6.0 before "unable to start" or "close as soon as it is opened":

Temporarily iReport-5.6.0 and previous versions do not support java8 environment.

So we can only use java6 or 7 environment.

If you really use the java8 environment. Had to install java after JDK6 or 7.

Find the path below the ireport file:

%IREPORT_HOME%\etc\ireport.conf

Edit the file below

Change jdkhome="/path/to/jdk" to the path of your JDK.

so. You don't have to delete the java8 environment.
