This can mostly solved by reserving some arbitrary high amount of memory before loading the rjava package or xlsx . 这可以通过在加载rjava包或xlsx之前保留一些任意大量的内存来解决。
options(java.parameters = "-Xmx4096m")
library(xlsx)
Sometimes this works fine, sometimes you need to restart the r session to make it work again. 有时这很好用，有时你需要重新启动r会话才能使它再次工作。 Somehow this is an issue with the garbage collection within java if to many functions are called in a to short amount of time. 不知何故，这是java中垃圾收集的问题，如果在很短的时间内调用很多函数。 Couldn't solve it 100% until now :-( 直到现在还无法100％解决:-(
