Sorry if this is something I overlooked and wasted some of your time, I thought changing the
target JRE and creating a new project would’ve taken care of this since I was already using
Java 1.8. 


As per the instructions I copied JRE into the FB…jre directory and the errors went


Thx again!!

Hi Carlos,




Where it says: 


Also, starting with Apache FlexJS 0.8.0, you will need to have upgraded Flash Builder to run
on Java 7 or 8.  See  <>


Someday we'll get this information ported over to Royale.

Thanks for the input, but the Flex compiler does not have an option “target” (I don’t
think so anyways) although I don’t think this is the problem I did try changing the JRE
compliance 1.6 and 1.7, FB does not seem to recognize JRE 1.8 (Windows -> preferences ->
Java -> compilers -> JDK compliance) .


I think the issue is with flexJS 0.8.0 itself because FlexJS 0.7.0 does not give an error.

Flash Builder 4.7 

Message: Uncaught exception in compiler Plug-in: com.adobe.flexbuilder.project

Exception stack trace:

ava.lang.UnsupportedClassVersionError: com/google/javascript/jscomp/ErrorManager : Unsupported
major.minor version 51.0


Looks like Flash Builder is getting java 7 (i.e. version 51) but is expecting Java 6 trying
"-target 1.6” as a compiler option may fix it.
