Re: Graal and Tomcat Native

Just a comment the function choosenum is not safe, the rand() is not a good PRG, i would use if it is possible arc4random in bsd/linux. Best Regards, Giorgio. El lun., 22 jul. 2019 a las 9:12, jean-frederic clere () escribió: > On 18/07/2019 11:05, Rainer Jung wrote: > > Hi Jean-Frederic and

Re: Graal and Tomcat Native

Hi Jean-Frederic and Rémy, I do not have a real answer, but a workaround. It is possible to get the same result without any printf style functions or atoi, just by doing arithmetics. But: maybe then the crash simply moves to another position. In src/ssl.c you can use: static int

Re: Graal and Tomcat Native

Probably not very helup, but to make sure, the GetEnv is failing, I would add a little code to native/src/jnilib.c in JNI_OnLoad() that creates an observable side effect while executing int he function. E.g. on Unix/Linux you could add something like #include ... FILE *fd =

Re: Graal and Tomcat Native

Hi Rémy, for which Java version and distribution is this? The docs for Java 7 and 8 are much less precise about return codes than the cited docs for Java 9. So older versions might give a generic error. The used code for checking versions is in the HotSpot sources for version 8 inside
