Hi everyone. Hoping for some help from the more experienced here!
After upgrading my Linux box (Fedora 32), i'm not able to run REW (5_20_beta_60) successfully. After installation and upon launching, i get this error:
Code:
SEVERE: Error during startup java.lang.NoSuchMethodError: org.jdesktop.swingx.util.OS.platformName(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
Unfortunately i'm a total noob to java. Searching around i couldn't find any refs to any 'platformName' method related to swingx.

But expecting this has something to do with my (new) java installation, as the previous one (Fedora 31, july this year) worked great with REW.

Any suggestions for things to check?

Thanks in advance!

Hi. Thanks for replying.

I did try that - "sudo dnf reinstall java-1.8.0-openjdk" - without luck.

Perhaps there's some java .jar which needs to be installed separately?

Here's the full traceback:

Code:
$ ./roomeqwizard

The OS platformName method is part of the code included in REW, REW only requires a Java 8 runtime. The runtime must not be headless, though if it was REW should still start but would have no audio I/O.

Is there a way to check whether my java installation is compatible with REW?

Here's the output of "java -version":
Code:
$ java -version
openjdk version "1.8.0_265"
OpenJDK Runtime Environment (build 1.8.0_265-b01)
OpenJDK 64-Bit Server VM (build 25.265-b01, mixed mode)

I took care to not use the 'headless' version of the 'java-1.8.0-openjdk'

Would normally expect a client VM rather than a server VM, server VMs tend to be headless.

Right.

Upon installing (using dnf) java-1.8.0-openjdk, java-1.8.0-openjdk-headless is pulled in as a dependency. Here's the available packages related to java-1.8.0:
Code:
$ dnf list all 'java-1.8.0*.x86_64'

Perhaps you are able to see anything here which should be substituted/avoided?

I can't find anything like that in the Fedora repos. According to the docs [here], the jre should be installed as part of the openjdk-devel package (which is installed here)

Did an attempt now with the latest java from oracle - jdk-14.0.2 - but observing the same error upon launching REW.

Forgive my java-noobness, but is there a way i could check my installation, to see if i've got the jre set up and running as expected?

Thanks for your patience! :-)

REW uses Java 8 only. You could try installing some earlier beta versions to see if the issue is specific to beta 60, they are available on the download History tab.

Thanks. I tried several versions from the download-history tab, all resulting in the same error upon launch, indicating there's something wrong with my current java install.... :-/

Do you know of any java test cases i could run, to check the jre i've got here now? I'll head for the Fedora java wikis to check if someone there has any suggestions.

Thanks a lot! I'll report back if/when i'm able to pinpoint the cause of my problem.

Hi again, seems i found a fix.

Scrapping my entire .m2 directory makes REW happy again :cool: Not sure what was in there which caused the pain. Now off to get those other things running again.

Currently running in Fedora fc32 (using the java-1.8.0-openjdk package).

Thanks for feedback and suggestions!
