Hi,

we can reproduce the hang during content assistent, it happens for us on a content assitent call on a helper class with CompileStatic that has some static methods. Entering the unkown class name and a valid static method name brings eclipse to freeze.
The plugin is the version: 2.9.2.xx-201611270046-e46

I have the following exceptions:

eclipse.buildId=4.6.1.M20160907-1200
java.version=1.8.0_112
java.vendor=Oracle Corporation
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=de_DE
Framework arguments:  -product org.eclipse.epp.package.jee.product
Command-line arguments:  -os win32 -ws win32 -arch x86_64 -product org.eclipse.epp.package.jee.product -clean
