ClassNotFoundException when profiling single class (JDK 10)

Steps to reproduce:
1) Create Anagram Game test project.
2) Select "Objects" in "Profile" button dropdown, click gear icon and verify "All Classes" is selected.
3) Begin profiling.
4) Find java.lang.String in class list. Either make "Selected" column visible and select class, or select "Profile Class" from context menu.
5) Click Apply button; the following exception is thrown:

java.lang.ClassNotFoundException: java/lang/reflect/WeakPairMap$Pair
at java.base/java.lang.Class.forName0(Native Method)
at java.base/java.lang.Class.forName(Class.java:291)
at org.netbeans.lib.profiler.server.ProfilerInterface$InitiateProfilingThread.initiateInstrumentation(ProfilerInterface.java:165)
at org.netbeans.lib.profiler.server.ProfilerInterface$InitiateProfilingThread.run(ProfilerInterface.java:117)

6) Click buttons in sample application; String class does not appear in profiler. This works correctly under JDK8 but fails with this exception under JDK10.
