And putback wants to putback the files in the SCCS dir:

putback -n

Looks like this is the culprit:

MakeJAR2.sh:cp -r ${TESTSRC}/ilib .
MakeJAR2.sh:cp -r ${TESTSRC}/bootreporter bootpath
This bug in MakeJAR2.sh affects the following tests:

    java/lang/instrument/NativeMethodPrefixAgent.java
    java/lang/instrument/RetransformAgent.java
