Issue loading Java Class

[franceme]

• Soot Version - 3.3.0_Nightly-With-Dependencies
• Java Version (Stable) - 1.7.80
• Java Version (Issue) - 1.8.192
• Steps to reproduce - I can attach steps to reproduce later if needed.

Currently within my project, this scenario reads in a single java file (*.java), loads it into Soot's Scene, scans it, and displays information.

The java class loading method (used and working in other scenarios) is as shown below.

Options.v().setsrc_prec(Options.src_prec_only_class);
Options.v().set_output_format(Options.output_format_jimple);
...
Options.v().set_prepend_classpath(true);
Options.v().set_whole_program(true);
...
Options.v().set_keep_line_number(true);
Options.v().set_allow_phantom_refs(true);
...
/**
 * Java File Package = tester
 * Java File = UrlFrameWorks.java
 *
 * variable clazz = tester.UrlFrameWorks
**/
Scene.v().loadClassAndSupport(clazz);

When the project is run on Java 1.7.80, the java file is loaded successfully and scanned with no issues.
However when run with the later Java Version (1.8.192), it throws a failure loading java.lang.CharSequence.
A trimmed excerpt of the stacktrace is shown below.

java.lang.Error: Error: Failed to load java.lang.CharSequence.

Is there an extra step to be called due to the version upgrade?

An important note to add, the java file being loaded may or may not have the entry point (main(...)) of the entire program.

I would like to add the following update.

It seems as though this is an issue when using any version of Java past 1.7.
I have found this due to the following other related issues: 775 and 896.

As the new question (or clarification), scanning Java source files (*.java) are not supported?

Unfortunately, the Java Source Code frontend is outdated.
I suggest to use Soot's ASM bytecode frontend. It supports more
language features and is more powerful.
