ERROR: JDWP Unable to get JNI 1.2 environment

Question

I get this error after debugging in Eclipse. The debug is successful though.

ERROR: JDWP Unable to get JNI 1.2 environment, jvm->GetEnv() return code = -2         


        

Answer 1

Happens on something as simple as this tutorial

//trim spaces
String s2 = "Welcome!";
int len1 = s2.length();
System.out.println(len1);
String s3 = s2.trim();
System.out.println(s3.length());

Happens if run program too fast multiple times so something to do with system performance?
