debugging not able to inspect the variables

Question

while debugging in eclipse
the problem is: String.hashCode() line: 1489 [local variables unavailable]
thus, not able to inspect the values of variables

Answer 1

JDK classes aren't compiled with debugging information, hence you can't see local variables during debugging. You'll have to rebuild JDK or use development version, see: Step through JDK source code in IntelliJ IDEA and Enabling debugging inside JRE classes.
