#19 StringIndexOutOfBoundsException : MethodInfo.parseDescriptor
When I try to decompile a class with Jdec 2.0, the following appears in the log:
[INFO]Magic Number of the Class "PotentialAssignees.class" Is CAFEBABE
[INFO]class Version is 50.0
Class File Version Number: 50.0 is not supported officially
However Jdec will try to decompile the class now.
To disable such class file decompilation , please specify false for skip_class_version_check in config.properties
