It seems that the error depends at least also on the version of the JRE. My version - where the error shows up is: java.runtime.name=Java(TM) SE Runtime Environment java.runtime.version=1.6.0_07-b06 java.specification.name=Java Platform API Specification java.specification.vendor=Sun Microsystems Inc. java.specification.version=1.6 java.vendor=Sun Microsystems Inc. java.vendor.url=http://java.sun.com/ java.vendor.url.bug=http://java.sun.com/cgi-bin/bugreport.cgi java.version=1.6.0_07 java.vm.info=mixed mode java.vm.name=Java HotSpot(TM) Client VM java.vm.specification.name=Java Virtual Machine Specification java.vm.specification.vendor=Sun Microsystems Inc. java.vm.specification.version=1.0 java.vm.vendor=Sun Microsystems Inc. java.vm.version=10.0-b23 Another setup where the error does not show up and the indexer appears to work as intended is with an older JRE: java.runtime.name=Java(TM) 2 Runtime Environment, Standard Edition java.runtime.version=1.5.0_13-b05-237 java.specification.name=Java Platform API Specification java.specification.vendor=Sun Microsystems Inc. java.specification.version=1.5 java.vendor=Apple Inc. java.vendor.url=http://www.apple.com/ java.vendor.url.bug=http://bugreport.apple.com/ java.version=1.5.0_13 java.vm.info=mixed mode java.vm.name=Java HotSpot(TM) Client VM java.vm.specification.name=Java Virtual Machine Specification java.vm.specification.vendor=Sun Microsystems Inc. java.vm.specification.version=1.0 java.vm.vendor=Apple Inc. java.vm.version=1.5.0_13-119
Thanks for the bug report. I will put the fix into CVS shortly, and it will be in the next build.
