> Through JVM Option +PrintInlining, we found that String has a constructor
> codeSize of 852, which is too large. This caused failed to inline.
>
> The following is the output information of PrintInlining:
>
> @ 9 java.lang.String::<init> (12 bytes) inline (hot)
> !m @ 1 java.nio.charset.Charset::defaultCharset (52 bytes)
> inline (hot)
> ! @ 8 java.lang.String::<init> (852 bytes) failed to
> inline: hot method too big
>
>
> In Java code, the big method that cannot be inlined is the following
> constructor
>
>
> String(Charset charset, byte[] bytes, int offset, int length) {}
>
> The above String constructor is too large; break it down into smaller methods
> with a codeSize under 325 to allow them to be inlined by the C2.
