Hi Andrew, Can you repro? If you can get it In the debugger there will probably be more info.
I think these are the release notes for JDK 1.8.0_291 https://www.oracle.com/java/technologies/javase/8u291-relnotes.html If I'm reading that right, lots of interesting changes in that release, like changes to TLS support, so maybe 291 can break something. -Alex On 7/10/23, 9:58 AM, "Frost, Andrew" <andrew.fr...@harman.com.inva <mailto:andrew.fr...@harman.com.inva>LID> wrote: EXTERNAL: Use caution when clicking on links or opening attachments. Hi all We have a customer with an odd issue and I wanted to check if anyone had found something similar already… The odd part about this is that it works fine with Java 1.8.0 build 201 but fails with Java 1.8.0 build 291, both of them 64-bit. The error is just when compiling an MXML file using Flex: Loading configuration file C:\FlexSDK\frameworks\flex-config.xml Error: null We have managed to narrow it down to the use of CFF: @font-face { src: url("Roboto-Regular.ttf"); fontFamily: Roboto; embedAsCFF: true; } Change the “true” to “false” and it compiles fine… In terms of version: >amxmlc.bat -version Version 4.6.0 build 23201 Although they’ve also tried with 4.16.1, adding in the old jar files using “ant thirdparty-downloads” which apparently still works. My thinking was that there’s an odd dependency upon the Adobe font embedding library, but I have never come across it working with one version of Java 1.8 and failing with another version of 1.8…. (and of course anything later also fails so they can’t just update to Java 11 or 17..) Does anyone have any hints or seen this sort of thing before? Many thanks Andrew
