Hi, Please review the fix for a shady bootstrapping issue, when a custom SecurityManager is using string concatenation: https://bugs.openjdk.java.net/browse/JDK-8155090
The essence of the issue is that during StringConcatFactory::<clinit>, we are reading the system properties via the privileged calls. When user SecurityManager that uses string concatenation is set, we are trying to produce a string concatenation stub in order to proceed, and double-back on SCF. There, we try to run SCF methods without fully complete <clinit>: the existing test fails with uninitialized static final Strategy field. The cleanest (yet subtle) solution here is to make sure the default SCF settings are good to run with, which allows transient <clinit> operations to complete normally: http://cr.openjdk.java.net/~shade/8155090/webrev.00/ Testing: offending test; java/lang/String jtregs Thanks, -Aleksey
