Failing jpackage tests with fastdebug/release build

I noticed that several jpackage tests are failing in my fastdebug builds, for example:

LANG=C LOG=info CONF=linux-x86_64-server-fastdebug make run-test TEST=tools/jpackage/share/jdk/jpackage/tests/BasicTest.java

fails with several stacktraces like this:
java.lang.AssertionError: Expected [0]. Actual [134]: Check command ["/home/rkennke/src/openjdk/lilliput/build/linux-x86_64-server-fastdebug/test-support/jtreg_test_jdk_tools_jpackage_share_jdk_jpackage_tests_BasicTest_java/scratch/0/./testWhitespaceInPaths/jumps over the lazy dog/WhitespaceInPathsBasicTest/bin/WhitespaceInPathsBasicTest"](1) exited with 0 code

at jdk.jpackage.test.TKit.assertEquals(TKit.java:567)
at jdk.jpackage.test.Executor$Result.assertExitCodeIs(Executor.java:183)

executing the package directly results in crash with coredump:
./build/linux-x86_64-server-fastdebug/test-support/jtreg_test_jdk_tools_jpackage_share_jdk_jpackage_tests_BasicTest_java/tools/jpackage/share/jdk/jpackage/tests/BasicTest/testWhitespaceInPaths/jumps\ over\ the\ lazy\ dog/WhitespaceInPathsBasicTest/bin/WhitespaceInPathsBasicTest

when running it in gdb, I am getting the following stacktrace:

the call into __cxa_pure_virtual () seems to indicate that the binary is linked such that it's calling into a pure virtual method.

Curiously, I cannot reproduce the problem with a slowdebug build.
It does reproduce with release and fastdebug builds.

Please let me know what I can do to help narrow the problem.
