Subject: InputStream returns -1 on EOF instead of throwing IOException
X-Git-Tag: v1.25.0~68^2
X-Git-Url: https://gerrit.simantics.org/r/gitweb?p=simantics%2Fplatform.git;a=commitdiff_plain;h=fc38c8c23e78b366b534e7230b67d0dd683cba66

InputStream returns -1 on EOF instead of throwing IOException

ClusterSupport2.getValueStreamBig now returns -1 when EOF is reached.
Previously it was invalidly throwing IOException (and before that very
invalidly throwing IllegalStateException).

refs #6741
