+
+Change made for Android
+
+1) Change coverage.out.file location in core/res/emma_default.properties to /data/coverage.ec
+2) Remove reference to sun.misc.* in core/java14/com/vladium/util/IJREVersion.java
+3) Remove reference to sun.misc.* and SunJREExitHookManager class from core/java13/com/vladium/util/exit/ExitHookManager.java
+4) Add java.security.cert.Certificate cast to core/java12/com/vladium/emma/rt/InstrClassLoader.java to fix compiler error
+5) Copy /core/res/com/vladium/emma/rt/RTExitHook.closure into source tree so it does not have to be generated in the build
