用eclipse很久了，不过最近老是遭遇个无法启动的问题，初始几次都是直接重新初始化workspace。也查过log，发现是subclipse这个插件的问题，不过将其SVN接口改为SVNkit一般能解决。今天实在忍无可忍，不想在治表阶段徘徊，狂google了一把，发现问题所在。
iusesvn.com发现这篇文章： eclipse使用subclipse导致jvm崩溃
Subclipse can crash on Windows if you have the environment variable
APR_ICONV_PATH set and it is pointing at a set of libraries that were
built against Apache 2.2. If that is the case, change the environment
variable name to APR_ICONV1_PATH and that will fix the problem. The
libraries from 2.2 will look for the variable with the "1" in it first
anyway. So this is a proper change to make.
If you want to be thorough, you could download the zip file for
Subversion 1.4.3, and point the APR_ICONV_PATH variable at the iconv
folder that came with it.
解决方法：
将环境变量 APR_ICONV_PATH改为APR_ICONV1_PATH
