> Hi all,
> The file src/java.base/share/native/libjli/java.c generate  false positive

> make jdk build error when configure with option `--enable-asan`. So I think

> build normally with configure option `--enable-asan`.
> This PR use gcc `_Pragma` to disbale the `-Wformat-truncation` compile 
> warning, to make the disable code area as small as possible, and make the 
> change looks ugly. There is another solution to disable the compile warning 
> seen as below, but it will disable the compile warning of java.c. So I use
