打不开是什么意思?能具体的解释一下吗?

你这个异常很有可能是表达式的书写有误,是用的lambda吧。

qq_38029602
qq_38029602 就是点击eclipse时候,会弹出一个小框,提示an error has occurred。See the log file. 然后去看日志文件里面报出数组下标越界的异常。 大兄弟,请问你知道怎么解决吗?

大家好
和我的错误一样,我这里是rsa9.6,(eclipse4.6),普通用户运行可以
run as administrator就出这个问题,eclipse就打不开了,什么原因呢

我正在考虑可能是一起rsa9.5一起安装的问题,

我昨天安装的,刚开始也报错,但是重新启动后好用了,今天20170106就不好用了

C:\Users\IBM_ADMIN\IBM\rationalsdp\workspace.metadata

eclipse.ini 里面的-vm调用的是自己的jdk,所以不好说是不是jdk版本的问题

-vm
jdk/jre/bin/javaw.exe
-startup
plugins/org.eclipse.equinox.launcher_1.3.200.v20160318-1642.jar
--launcher.library

-Dcom.ibm.ws.management.event.max_polling_interval=1000

和我的一样,加我qq 402235823,好使了一个晚上
