JD-GUI below version 0.3.2 are able to explore these packages, but all versions above 0.3.1 to 0.3.7 RC1 giving this error (either exploring from left tree-view window or using Ctrl+Shift+T):
"An unhandled exception occured. Press "Abort" to terminate the program, "Retry" to exit the program normally and "Ignore" to try to continue."
Can anyone share links where I can download jd-gui below version 0.3.
