Subject: [PATCH] fix cp_infos_from_context()

while reading constant pool we should skip one index in result after long and double constants.
i.e. we shoud add dummy const after long or double constant;

index after long and double reserved: https://docs.oracle.com/javase/specs/jvms/se21/html/jvms-4.html#jvms-4.4.5
