Why am I getting an AssertionError when assigning Arrays.asList() to var directly?

java arrays exception type-inference java-10

It is only reproduced when javac is called with a -g flag.

Possible workarounds:

Do not use the -g flag
- If you use IDEA: Settings → Build, Execution, Deployment → Compiler → Java Compiler → Uncheck "Generate Debugging Info"
Do not use var with intersection types (use explicit types):
- List<Object> list = Arrays.asList(1L, 2.0F, "3");
- var list = Arrays.<Object> asList(1L, 2.0F, "3");
Use Eclipse which has its own compiler

UDPATE:

The bug was fixed in JDK 10.0.2.

This is a bug of openjdk, see this:

Javac should skip non-denotable types in the LocalVariableTypeTable attribute
